\fData Analysis and Application (DAA) Template Use this file for all assignments that require the DAA Template. Although the statistical tests will change from week to week, the basic organization and structure of the DAA remains the same. Update the title of the template. Remove this text and provide a brief introduction. Section 1: Data File Description 1. Describe the context of the data set. You may cite your previous description if the same data set is used from a previous assignment. 1 Specify the variables used in this DAA and the scale of measurement of each variable. Include a definition of the specified variables (predictor, outcome) and corresponding scales of measurement. Variables are gender and GPA 2. Specify sample size (N).

Paste SPSS descriptives output showing skewness and kurtosis values for gpa and interpret them. Paste SPSS output for the Shapiro-Wilk test of gpa and interpret it. Report the results of the Levene test and interpret it. Summarize whether or not the assumptions of the t test are met. Summarize whether or not the assumptions are met. If assumptions are not met, discuss how to ameliorate violations of the assumptions. Section 3: Research Question, Hypotheses, and Alpha Level 1. Articulate a research question relevant to gender and gpa. 2. Articulate the null hypothesis and alternative hypothesis. 3. Specify the alpha level.
