[Q] Am I using the right tests?

Hi all,

I am trying to complete statistical analyses for a medical project regarding 2 different exposures .

Some of the outcomes are numeric, such as the number of migraines patients experiences, and others are categorical, such as presence or absence of heart attack.

My plan is the following:

1. Do **t-test with unequal variance** for the numeric values. ex: t-test to compare the number of migraines or minutes spent in surgery for the 2 patient cohorts
2. do **chi-square for the categoricals**: ex: chi-square to compare the presence or absence of heart attack in patients receiving med A vs those receiving med B

I will mostly be using excel for this project.

I am happy to provide more info if needed

Thank you for any feedback or recommendations!
