    My dependent variable is ordinal. Which regression test should I use?




    Hi guys!

    I am interested in running a regression to see the effects of some psychological variables (both continuous and categorical) on the performance on a decision making task. The problem is that my dependent variable (the task performance) is ordinal i.e., it is the total number of correct answers provided by my participants, ranging from 0 to 9. Now, I am not sure what type of regression I should run. I have been looking at the literature and I have noticed that some papers treated similar dependent variables as scales and run linear regressions. However, I also found that the ordinal regression and the Poisson regression could be other valid alternatives. Which test would you suggest me to use?

    I would also like to see whether a high score in one independent variable can compensate for a low score in another independent variable by looking at the performance at the task. Is there a way to see it from the regression model?

    Many thanks for your help.

    Chiara

    Try ordinal logistic regression.
