Homework: Statistics
Part I: Data Screening for between Groups
Using the variables selected in Module: Pick Topic, formulate a problem statement that tests for differences between two groups.
Based on the problem statement, write a research question and a null and alternative hypothesis.
A. Name the variables, the instrument used to measure the variables, and the variable level of measurement.
B. Describe and present the descriptive statistics for the study variables. You should include several sentences describing any notable outcomes to the descriptive statistics and provide the appropriate tables to show the descriptive statistics.
C. Identify the statistical analysis you will use to test for differences between the two groups. Explain why you selected this analysis.
D. Complete the data screening/tests of assumptions for the selected statistical analysis. You must identify each assumption, describe how it was tested, and describe the outcome of that test. Include relevant tables and figures to demonstrate your work. See Warner I (pp. 332-338).
E. Write up the conduct of the data screening. In a narrative format, you must describe the problem statement, research question, and hypotheses. You must describe the testing of assumptions and the outcomes of those tests. Using proper APA formatting, include all tables and figures demonstrating the results.
Part II: Group DifferenceS Results
Based on the work completed in Module, Data Screening Output for Between Groups Homework, write a research question and a null and alternative hypothesis.
A. Identify the statistical analysis you will use to test for differences between the two groups. Explain why you selected this analysis.
B. Complete the appropriate statistical analysis to determine if there is a difference in the dependent variable between the independent variable groups. Get the instant assignment help.
C. Report the results of the hypothesis testing.
D. Report the statistical results including the effect size, Cohen's d. Include the relevant table(s) from SPSS.
E. Write up the conduct of the analysis and the results. In a narrative format, you must describe the problem statement, research question, and hypotheses. You must describe the conduct of the analysis and then report the results of the appropriate statistical test(s). Using proper APA formatting, include all tables and figures demonstrating the results. Relate the meaning of the results back to the original research problem and research questions.
