Statistical Help

If you are struggling with statistics, it is time to get statistical help. And while it might not be easy for you to admit that you actually need help, once you seek statistical help, you will be very glad you have done so, for statistical help can assist you with any statistical issue you might be having.

Statistical help is available to anyone who needs help with statistics (hence the name statistical help). Because statistics is a science, it requires that precise methodology be followed and adhered to. For people who are not trained in statistics (and who don’t seek statistical help), this can be very difficult. These people who are not trained statisticians and need statistical help sometimes turn to the internet for their statistical help. And while this is a good instinct, for seeking help and trying to do it on your own is very good in some cases, in the case of statistics, this can often have disastrous consequences.

Let’s say, for example, a student who needs statistical help turns to the internet for statistical help. That student reads-up on statistics and spends hours and hours researching the proper methodology for his or her project. Well, in reality, the study of statistics takes weeks and months, if not years to perfect. In fact, entire courses are designed in statistics. Thus, quickly reading and researching information about statistical procedures on the internet will not provide a student with the statistical help he or she needs.

Continuing with this example, let’s say this student, armed with hours of internet research on statistics, continues with his or her dissertation by conducting the necessary research. This student (who has not acquired proper statistical help) then gathers data. And again, while the practice of using the intent can sometimes be good (the student wanting to do it on his or her own, again, is a good instinct) the outcome can be very painful. For it is likely that a student who is not trained in statistics and who does not seek appropriate statistical help will falter in the data gathering step of statistics. And this step is extremely important if one is to obtain accurate and valid statistics. That student then relies on faulty data (data that is biased, for example, or data that has been obtained with an improper sample size), and this faulty data leads to faulty conclusions and inferences. Thus, because this student did not get the right kind of statistical help, he or she must start all over. And there is nothing more time-consuming and frustrating than starting a dissertation from the very beginning.

Instead of trying to do all of the statistics on his or her own, that student should turn to statistics consultants for statistical help. Statistics consultants can give statistical help thereby ensuring that the student is performing the proper statistical methodology. Additionally, statistics consultants can ensure that the student has accurate and precise results. Statistical help, then, can step-in to help and assist the student so that he or she does not make mistakes in the statistical portion of their analysis.

Statistical help provided by statistical consultants provides effective, efficient and accurate results. This is because statistical help is provided by trained and expert statistical consultants who know everything there is to know about statistics. The experts who provide statistical help know, for example, how to gather accurate data, how to interpret that data, how to use statistical tests to accurately read that data, and how to apply those results to a dissertation or project.

Statistical help is also very affordable. This is especially true when considering the time that is often spent making mistakes and starting over because of a statistical procedural mistake. Statistical help provides accurate and on-time results and for this reason, statistical help is well worth the investment. And while the process of statistics can be time-consuming and laborious, with the right statistical help, a student can finish with success.

Statistical Help

Statistics is a mathematical science that is used for data analysis, interpretation, explanation and presentation of data. Statistical help is required in every field, whether it is Psychology, medical/nursing or business. This article will highlight some key concepts of statistical help in psychology research. In psychology, a number of researches are conducted to know the attitude or behavior of people, etc. Whenever a research study is conducted, statistical help is required to analyze the data and interpret the results. Statistical help starts from the research methodology and goes through the presenting of the results.

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.
