Hello Folks,

I have 5 years of data on GPA, credit completions etc. and several categorical variables ( ex. gender, ethnicity, age). I have tried using Anova and Chi-squared to test whether for significant difference between groups over the 5 years. I think Chi-squared would be the appropriate test but the only software available to me is minitab. I am not sure if I am using the correct test to see if credit completions was different by gender over 5 year. I have the raw data and summary data. I would appreciate any guidance with this project.
Please let me know if I need to explain further.
Thank you kindly,
