Should I use Bonferroni correction?

#1
Hi.

I‘m analzying the influence of Yoga on stress adadption and work related stress. I tested the differences of work related stress between pretest and posttest in the experimental group by a paired t-test. I also tested the differences of stress adaption between pretest and posttest in the experimental group. Should I use the bonferroni correction to minimize the alpha error because I have 2 different tests or is it independent from each other? When do I use the bonferroni correction? Thanks for the help

For answering your research question, you can calculate the individual differences between pre and post,
and use this difference as the dependent variable in a t-test for independent groups.
