A measure of central tendency.
A measure of central tendency
For this assignment, you will select and create a fictitious data sets using information from the APA.org site to demonstrate your skills in the basics of statistical analyses. You will need to:
Describe your research question.
State a hypothesis.
List and explain the variables you are using from the dataset. Should you design a study with just two variables, make a recommendation for a third variable and how that might add to interpretation of the data.
Select a random sample of data from your dataset. The data should have a minimum of 30 cases, but not more than 200 cases. (Hint: You can use the “random” function in either Excel or SPSS to generate a random sample from your dataset.)
Conduct a descriptive data analysis that includes the following:
a measure of central tendency
a measure of dispersion
at least one graph
Briefly interpret the descriptive data analysis.
Conduct the appropriate statistical test that will answer your hypothesis. It must be a statistical test covered in this course such as regression analysis, single t-test, independent t-test, cross-tabulations, Chi-square, or One-Way ANOVA. Explain your justification for using the test based on the type of data and the level of measurement.
Report and interpret your findings. Use APA style and include a statement about whether you reject or fail to reject the null hypothesis. Here are some resources that will help you with APA formatting in this step:

Copy and paste your Excel or SPSS data output and place it in an appendix.
