APA Citation
APA citation has a purpose, and the purpose of APA citation is so others can look up and access all resources cited in a paper. Thus, proper APA citation will allow all information, data and research to be checked and verified. This is most definitely an important feature of dissertations as proper APA citation allows for a dissertation to be pronounced as valid.
Many students struggle with APA citation because many students are not familiar with APA citation. Further, APA citation can seem unimportant as the student and writer of the dissertation is more concerned with the larger aspect of the dissertation, like the research and analysis involved in the dissertation. Thus, APA citation can seem minor in comparison to the larger point the student is making. And yet, the dissertation will not be accepted if it does not have proper APA citation. In other words, proper APA citation can be an annoying task, but proper APA citation is absolutely necessary.
APA citation has two major parts. These two parts of APA citation are in-text citations and the reference list for APA citation. The in-text citations for APA citation occur within the document. In other words, there is a proper way to apply APA citation to text within the document. The second part of APA citation occurs at the end of the document, in the reference list or bibliography part of the paper. There is a very specific way to cite everything in the reference list if the dissertation is to follow proper APA citation.
APA citation also follows many formatting guidelines, most of which are unique to APA citation. Thus, APA citation includes formatting for every aspect of the dissertation. In other words, there is APA citation for the title page, APA citation for the page numbers, APA citation for the running head of a dissertation, APA citation for the abstract, APA citation for the visuals, APA citation for headings, and, as previously mentioned, APA citation for the reference list. Clearly then, APA citation will happen on every single page of the dissertation, be it to properly cite sources, data and research or to diagram charts and graphs.
Because many students are concerned with citation (as well they should be since APA citation plays a major part in the dissertation) APA citation help is available. APA citation help will dramatically cut-down on the time that a student needs to spend on his or her thesis. This is particularly important because often-times students do not know how APA citation works and they wait until the last minute to figure out how APA citation should fit into their dissertations. Thinking that using APA citation will be an easy concept to grasp, students do not plan enough time to fix and edit their paper so that it is has proper APA citation. In other words, many students finish their dissertations, but these “finished” dissertations are not finished at all because they are not in adequate APA citation. Thus, students are under much stress and pressure as they must quickly figure out how to put their paper into proper APA citation. APA citation, however, is not something that can be done so quickly! In fact, entire books have been written on proper APA citation—and because this is the case, many students are overwhelmed with the daunting task of changing, editing and reformatting their paper. APA citation help is available, however, and with the help of an expert in proper APA citation, the student will no-doubt truly finish their dissertation before the ever-looming deadline.

Statistics Consulting
First, let’s look at how individuals can use statistics consulting and statistics consulting firms. Most often individuals get statistics consulting help and contact statistics consulting firms when they need help with a large project that involves statistics. This is most often the case for doctoral students who need to write their dissertations. Dissertations, however, require mass amounts of time. Statistics consulting and statistics consulting firms can help these time-strapped students. In fact, if a student seeks statistics consulting from a statistics consulting firm, the student is guaranteed to save both time and energy. This is true because statistics consulting can help from the very beginning of the project and statistics consulting firms will see this project through until it is completed.
Thus, statistics consulting is essential as statistics consulting firms ‘jump in’ at the very beginning of a project. The beginning of the project is the actual choosing of the topic. Many students do not even know where to start when it comes to their dissertations, and this is where statistics consulting provided by statistics consulting firms can begin. Statistics consulting provided by statistics consulting firms will help the student narrow-down the options of their topic. Statistics consulting provided by statistics consulting firms gives valuable feedback to students because they are trained and experienced. Statistics consulting provided by statistics consulting firms is especially helpful for first-time dissertation writers as these students often struggle most. Not only have these ‘first-timers’ never written a dissertation before, they are often-times overwhelmed by the magnitude and scope of the project. Statistics consulting provided by statistics consulting firms, however, are not intimidated as statistics consultants have expertise in the subject and are prepared to help.
Once the topic for the project is decided, statistics consulting provides a timeline for the students. This timeline provided by statistics consulting gives students much-needed targets. Thus, statistics consulting helps organize students and statistics consulting provides step-by-step instruction on what needs to be done and in what order.
Statistics consulting then helps the student with every single aspect of his/her project. This includes gathering the data, analyzing the data and applying all the necessary principles, assumptions and rules to the data gathering and analyzing. This is especially hard for students as students are not always trained in statistics. Statistics consulting provided by statistics consulting firms, however, provides all of the information, guidance and assistance necessary as they carry-out and explain all of the statistics procedures. Statistics consulting, for example, explains how research needs to be gathered—be it by questionnaire, on-line survey, telephone interview, etc. Statistics consulting then explains how a student needs to interpret the results of the data they collect. Statistics consulting explains, for example, the assumptions, rules and tests of statistics (for example, ANOVA, ANCOVA, MANOVA, etc). In other words statistics consulting provided by statistics consulting firms will go through every single aspect of acquiring, organizing and processing the data that the student collects and statistics consulting firms will ensure that the dissertation is complete.
Students, however, are not the only people that can benefit greatly from statistics consulting provided by statistics consulting firms. Statistics consulting firms can also help organizations and businesses as it can deliver information about how to maximize profits. Additionally, statistics consulting provided by statistics consulting firms can help in fields such as psychology, medicine, nursing and government. This is true because all of these fields require statistics.
Acquiring statistics consulting is easy as there is much statistics consulting available through statistics consulting firms. Statistics consulting is also very affordable as statistics consulting saves time and energy, which in turn saves money. Statistics consulting provided by statistics consulting firms is well worth the cost as statistics consulting provides valid and accurate results in all fields requiring statistics. Statistics consulting will no doubt ensure success for both the individual and the organization.
Independent Sample T-Test
Assumptions in independent samples t-test:
1. Independent sample t-test assumes that the dependent variable is normally distributed.
2. Independent sample t-test assumes that the variance of the two groups are the same as the dependent variable.
3. Independent sample t-test also assumes that the two samples are independent of each other.
4. Samples for independent sample t-test are drawn from the population at random.
5. In independent sample t-test, all observations must be independent of each other.
6. In independent sample t-test, dependent variables must be measured on an interval or ratio scale.
Procedures for independent sample t-test:
1. Set up the hypothesis for independent sample t-test.
a. Null Hypothesis: In independent sample t-test, null hypothesis is assumed when the means of the two groups are not significantly different.
b. Alternative Hypothesis: In independent sample t-test, Alternative hypothesis assumes that the means of the two groups are significantly different.
2. Calculate the standard deviation for the independent sample t-test by using this formula:

V= degree of freedom
N1+N2= number of observations in both samples of the independent sample t-test.
5. Hypothesis testing: In hypothesis testing for the independent sample t-test, statistical decisions are made about whether or not the two population means are identical. Compare the calculated value of the independent sample t-test with the table value of the sample t-test. If the calculated value of the independent sample t-test is greater than the table value of the predetermined significance level, we will reject the null hypothesis and say that the means of the two groups are different. If the calculated value of the independent sample t-test is less than the table value, then we will say that the means of the two groups are the same.
Independent sample t-test and SPSS: Most statistical software has the option to perform the independent sample t-test. In SPSS, to perform the independent sample t-test we have to perform following procedure:
2. Click on the “open data” icon and select the data for the independent sample t-test.
3. Click on the “analysis” option and select “compare mean” from the analysis option.
4. Select “independent sample t-test” from the compare mean option. As we click on the independent sample t-test, the following window will appear:
Independent sample t-test group statistics table: This table will show the total number in each group, the mean, the standard deviation and the standard error for the independent sample t-test.

APA Formatting
The APA in APA formatting stands for the American Psychological Association, and APA formatting is a set of rules and guidelines that a student must use to make sure that all information that the student presents is done in a clear and consistent manner. Thus, most dissertations are written using APA formatting and most dissertations cannot get approved without proper APA formatting.
Because the dissertation is one of the most important aspects of a student’s academic life, APA formatting, which is a part of that dissertation, is extremely important. And yet, few students have much knowledge or expertise in APA formatting. This is because many professors do not actually teach APA formatting. Instead, they expect students to already know proper APA formatting, or to figure it out for themselves. This, of course, is unfortunate for the student who is already strapped with the burdens of the actual dissertation. This problem can be solved, however, as there is much guidance and assistance available to ensure proper APA formatting of dissertations.
Proper APA formatting requires that a writer follow many rules and regulations. These rules and regulations of format can be quite irksome. In other words, often times it feels like APA formatting is a “nit-picky” detail, and for that reason, it can be very frustrating to take the time needed to format a paper in proper APA formatting.
APA formatting is not a style of writing, and APA formatting will not change the content of the dissertation. It will also not change any of the research or analysis. Proper APA formatting will, however, change the way that the content is cited and presented.
The list of APA formatting rules and guidelines is extensive. In fact, APA formatting is so extensive that is has its own reference manual. In other words, APA formatting is by no means something that a student can expect to “pick-up” easily. This is especially true for students who are writing their dissertation, as students often realize the importance of APA formatting at the very end of the dissertation. Thus, their entire dissertation is written without proper APA formatting and needs to be changed! The student then realizes just how time consuming it is to convert his/her entire dissertation into standard and proper APA formatting.
Clearly students can benefit from consultants who specialize in APA formatting. Consultants who specialize in APA formatting can ensure that the entire dissertation is formatted correctly and they can assist students in all things relating to formatting and style. Though APA formatting consultants are easy to find, it is important to do research on the APA formatting consultant that you choose. This is because many APA formatting consultants are not well qualified. The right APA formatting consultant, however, can save a student from having to deal with frustrating details that require a large amount of time to fix. Thus, APA formatting consultants are well worth the money, as they save the student from having to waste his/her valuable time. Additionally, an APA formatting consultant can ensure that the dissertation is approved as the consultant will ensure that everything is cited properly and that all formatting issues are standard and proper. This will clearly ensure success for the time-strapped student.

Dissertation Consulting
Dissertation consulting is an important form of assistance to the doctorate aspirant. Through dissertation consulting, the students attain guidance and direction on how to go about the whole dissertation process. Dissertation consulting is convenient and easily accessible. The results achieved through dissertation consulting are worthwhile and reliable. Dissertation consulting can be attained from qualified personnel like professors, statisticians and consultants. They must, however, be experienced and trained to provide dissertation consulting services to the students. Dissertation consulting services require the consultant to possess certain qualities to carry the project through successfully. Statistical knowledge, a scientific outlook, computer proficiency and good communication skills are necessary traits for the expert providing the dissertation consulting services. With the growing importance of statistics in the present day, students require professional help to ensure good results. They cannot single-handedly complete the dissertation unless they are equipped with statistical skills and competence. In such cases, most of these struggling students turn to dissertation consulting.
In the case of students studying subjects like psychology, medicine and nursing, and business, where statistics is an utmost necessity, dissertation consulting is required. Psychology students conduct experimental tests where statistics and dissertation consulting play pivotal roles. The student, who may not be trained with statistics, turns to dissertation consulting. Dissertation consulting is helpful for students pursuing their careers in medicine as well. Again, statistics is required for performing clinical trials and determining medical errors. This can be done lucratively with the help of dissertation consulting. Business is another line of study where dissertation consulting is effective. Business involves market and financial research, econometrics, auditing etc., and this includes statistical and professional assistance through dissertation consulting services. Dissertation consulting is thus necessary, especially for students pursuing these fields. This is because important terms like standard deviation, standard error of the mean, over-analysis of data, multiple comparisons, and the like are frequently used in these subjects. These complicated statistical procedures emphasize the need for dissertation consulting services.
In fact, dissertation consulting caters to almost every field of study. Science and medicine, social sciences like psychology and sociology, business and commerce and even law and administration all require dissertation consulting facilities. Surely, every student deserves the right at a fair chance of improving their grades. Dissertation consulting is a solution.
The professionals executing dissertation consulting aide the student throughout the entire process, including helping students with choosing the topic, researching and investigating, designing the research pattern, conducting tests, questionnaires and surveys, formulating various statistical approaches, reviewing and analyzing the results, interpreting the results into simple language, and finally, concluding the assistance with a final check and editing of the dissertation. Dissertation consulting has proven very beneficial to the students. Through professional help and assistance very much within the average individuals’ means, dissertation consulting has been incredibly helpful for students.
Dissertation consulting also ensures that the consultants adhere to deadlines and do their best to present the best services to students. Good grades and results are a surety when it comes to the help acquired through dissertation consulting.

Statistical Help
Research methodology: In psychological research, statistics helps us to determine the methodology for the study. For example, what should the sample size for that particular research be? Which technique should we apply to the data, etc.?
Statistical help in research design: In psychological research, two types of research designs are used. The first type of research design is the true experiment, which is used when a random sample assignment is used. The second type of research design is used with multiple measures, including quasi-experiment and non experiment research designs.
Selection of variable: Statistical help is used in psychology for the selection of a variable. Variables are selected on the basis of predetermined theory that is statistically tested.
Sample size: In psychological research, we need statistical help in selecting the sample size. We know that when the sample size is small, the statistical test will not give accurate results. If the sample size is too large, then it will take more time and will be costly as well. For example, if we are using regression methods, then the minimum of 10 observations per independent variable should be present in the research data. We can use statistical help to determine the adequate sample size.
Data mining: In psychological research, there are two ways of data collection, namely the primary research and the secondary research. Statistical help gives an idea about which technique we should use for data mining.
Test statistics: In psychological research, we use statistical help do determine the test statistics for that particular data. There are a number of techniques where statistical help is required for decision making. For example, t-test, Z-test, and ANOVA, are some parametric tests by which statistical help is provided to us for comparing the mean of two behaviors. Non- parametric tests like Mann-Whitney, Kruskal-Wallis, and chi-square tests are the tests that can be carried out through statistical help to answer certain research questions. This will clearly help us in the field of psychology. Logistic regression provides statistical help when the dependent regression variable is nominal. Structural equation modeling technique is usually used in psychological research. SEM techniques provide statistical help to observe the new variables from the unobserved variables and then to test the relationship between them.
Validity and reliability of statistical result: In any research, conducting analysis is not enough. After conducting the analysis, we have to test that the result is valid and reliable. Statistical help gives us the freedom to test the reliability and validity of the result.
Interpretation of result: Statistical help gives us ideas to interpret the results of the research and it gives us ideas as to how to present those results.
Statistical consultant: Statistical consultants have much experience and a strong knowledge of statistics techniques and the theory of psychology. They therefore provide statistical help. Ideally, the consultants are people who have the required education to provide statistical help. Students, researchers or doctors can hire statistical help.

Doctoral Statistical Analysis
Hiring doctoral statistical analysis help assists the students to reach more precise, steadfast and dependable results. The doctoral statistical analysis may involve different fields of subjects but its statistical part is a kind of mathematical science. Doctoral statistical analysis involves the assemblage, assessment and summarization of data. Doctoral statistical analysis also has methods and techniques in which the analysts and consultants understand, alter and interpret the data to determine some patterns for their research and its intended conclusion. Though doctoral statistical analysis only caters to the students in universities, the students who do the doctoral statistical analysis often use their knowledge in business problems, consulting projects, etc. Doctoral statistical analysis can also help them in market and clinical researches in their future life. Thus, doctoral statistical analysis and the knowledge gained in learning how to do statistical analysis can go a long way for the student—both in his studies and beyond the university.
Doctoral statistical analysis is very effectual and instructive for students from every field and subject. Since statistics analysis includes data collection, data interpretation and data validation, doctoral statistical analysis uses statistical methods to prove certain innovative points and issues of the doctoral statistical analysis. While the students are doing their doctoral statistical analysis, they examine the data very efficiently and they also design and structure different techniques and procedures for data collection. Through doctoral statistical analysis, a student is able to extract the useful points of his/her thesis and therefore, it becomes the most definite step in order to procure the success of his/her thesis. Doctoral statistical analysis also provides guidance to the students for their entire project and its execution. The number of advantages of doing the doctoral statistical analysis is immense and incalculable.
All psychology students use statistics in their doctoral statistical analysis, where they have to carry out surveys and questionnaires in order to understand some human behaviors. Psychology is a behavioral science where students carry out surveys to understand certain human behavior. A PhD student can also utilize doctoral statistical analysis to prove his/her individual point about men and the reasons for their diverse behaviors. Medical students, who are doing their theses, can also utilize doctoral statistical analysis for understanding the causes and prevention of certain diseases in one particular area. For instance, if their research is about the maximum number of malaria patients in South Africa, they can very appropriately conclude their results through doctoral statistical analysis. Similarly, nursing students doing their nursing doctoral statistical analysis or business doctoral statistical analysis can benefit from doctoral statistical analysis.
Clearly we can see that statistical analysis has its own importance in every field possible. Students who do not have a statistical background sometimes feel struck while going through their doctoral statistical analysis. They should never ignore their doctoral statistical analysis because it is the most important tool for them to gain validity for their thesis. They should never hesitate to get help, or to hire help from statistical analysts who are easily available online and who provide valid and concrete doctoral statistical analysis help.

Analysis of Variance
Additionally, it can be used in cases of two samples analysis of variance (ANOVA) and results will be the same as the t-test. For example, if we want to compare income by gender group. In this case, t-test and analysis of variance (ANOVA) results will be the same. In the case of more than two groups, we can use t-test as well, but this procedure will be long. Thus, analysis of variance (ANOVA) technique is the best technique when the independent variable has more than two groups. Before performing the analysis of variance (ANOVA), we should consider some basics and some assumptions on which this test is performed:
Assumptions:
1. Independence of case: Independence of case assumption means that the case of the dependent variable should be independent or the sample should be selected randomly. There should not be any pattern in the selection of the sample.
2. Normality: Distribution of each group should be normal. The Kolmogorov-Smirnov or the Shapiro-Wilk test may be used to confirm normality of the group.
3. Homogeneity: Homogeneity means variance between the groups should be the same. Levene's test is used to test the homogeneity between groups.
If particular data follows the above assumptions, then the analysis of variance (ANOVA) is the best technique to compare the means of two populations, or more than two populations. Analysis of variance (ANOVA) has three types.
One way analysis of variance (ANOVA): When we are comparing more than three groups based on one factor variable, then it said to be one way analysis of variance (ANOVA). For example, if we want to compare whether or not the mean output of three workers is the same based on the working hours of the three workers, then it said to be one way analysis of variance (ANOVA).
Two way analysis of variance (ANOVA): When factor variables are more than two, then it is said to be two way analysis of variance (ANOVA). For example, based on working condition and working hours, we can compare whether or not the mean output of three workers is the same. In this case, it is said to be two way analysis of variance (ANOVA).
K way analysis of variance (ANOVA): When factor variables are k, then it is said to be the k way of analysis of variance (ANOVA).
Key terms and concepts:
Sum of square between groups: For the sum of the square between groups, we calculate the individual means of the group, then we take the deviation from the individual mean for each group. And finally, we will take the sum of all groups after the square of the individual group.
Sum of squares within group: In order to get the sum of squares within a group, we calculate the grand mean for all groups and then take the deviation from the individual group. The sum of all groups will be done after the square of the deviation.
F –ratio: To calculate the F-ratio, the sum of the squares between groups will be divided by the sum of the square within a group.
Degree of freedom: To calculate the degree of freedom between the sums of the squares group, we will subtract one from the number of groups. The sum of the square within the group’s degree of freedom will be calculated by subtracting the number of groups from the total observation.
BSS df = (g-1) for BSS is between the sum of squares, where g is the group, and df is the degree of freedom.
WSS df = (N-g) for WSS within the sum of squares, where N is the total sample size.
Significance: At a predetermine level of significance (usually at 5%), we will compare and calculate the value with the critical table value. Today, however, computers can automatically calculate the probability value for F-ratio. If p-value is lesser than the predetermined significance level, then group means will be different. Or, if the p-value is greater than the predetermined significance level, we can say that there is no difference between the groups’ mean.
Analysis of variance (ANOVA) in SPSS: In SPSS, analysis of variance (ANOVA) can be performed in many ways. We can perform this test in SPSS by clicking on the option “one way ANOVA,” available in the “compare means” option. When we are performing two ways or more than two ways analysis of variance (ANOVA), then we can use the “univariate” option available in the GLM menu. SPSS will give additional results as well, like the partial eta square, Power, regression model, post hoc, homogeneity test, etc. The post hoc test is performed when there is significant difference between groups and we want to know exactly which group has means that are significantly different from other groups.
Extension of analysis of variance (ANOVA):
MANOVA: Analysis of variance (ANOVA) is performed when we have one dependent metric variable and one nominal independent variable. However, when we have more than one dependent variable and one or more independent variable, then we will use multivariate analysis of variance (MANOVA).
ANCOVA: Analysis of covariance (ANCOVA) test is used to know whether or not certain factors have an effect on the outcome variable after removing the variance for quantitative predictors (covariates).
