Please describe the SPSS file in the following detail:
1. For legal compliance you should show that either your selection tests do not discriminate based on gender and race/ethnicity or you have to show that they are job related. It is best if you can show both. In lesson two you learned how to test for group differences. In this case there is a variable with the label GenderID, a variable with the label “Race Description” and another that has the label “Hispanic/Latino”. The first measures gender, the second measures race, and the third measures ethnicity. The gender and Hispanic/Latino variables are dummy variables, so you can use Independent Sample t-tests, which you have already done. The race description variable has five categories so you would need to use ANOVA to test for differences between groups on your three selection tests: Cognitive test, Job/Person Fit test, and the Structured Interview. You also have a variable that references whether they were recruited through a diversity job fair. It is a dummy variable, and you can see if there are differences in the Cognitive test, the Job/Person Fit Test, and the Structured Interview if they were recruited through a diversity job fair or not.
Test for those differences and then describe what you find.
2. . In this data set you have a list of employees who have left the organization and those who are still with the organization. There is a variable labeled “Terminated”. It is a dummy variable. 0 means they are still employed and 1 means that their employment has been terminated. You want to see if your Cognitive Test, Job-Person Fit Test, and Structured interview will predict turnover. If they do it provides additional job-related information that can be used to validate your selection tests. You can not use multiple linear regression for this test, because Multiple Linear Regrssion requires that the dependent variable be a continuous (or at least ordinal) variable. However, “Terminated” is only a dummy variable. They either quit or did not quit. SPSS has a tool that allows you to evaluate a binary variable. It is called logistic regression. View the tutorial video about running logistic regression. Terminated is the dependent variable. Cognitive test, Job-person Fit Test, and Structured Interview are the covariates. Run the test and report what you learned.
