Which Regression Model should I Use

[nafta90]

Hello,

I have a data set of students and I need to fit a regression model to predict the probability of a student will graduate college with a GPA => 3.4 or lower. I will be using age, gender, race and high-school GPA as my explanatory variables.
Do I need a logistic or linear regression and how do I set it up?

Thank you,
Alex

What is your sample size and what is the outcome proportions?

What is your sample size and what is the outcome proportions?

I have 150 observations and 53% are over 3.4.

Are you planning to build the model using your data, then use that model to get the probabilities of the students used to build the model?

I need to build the model, get the coefficients and interpret them as to which ones are significant in predicting the graduating GPA being over 3.4.
