I need some help. I'm a full on Arts-and-Humanities person, but I need some stats!

**Here's the story:**

1. Two groups of participants: Group 1 got the treatment, Group 2 didn't.

2. I've calculated the difference in their scores from the pre-test and the post-test (on 5 different tests). I've also been able to work out the means in an independent t-test.

3. There are 7 variables that I can think of at the minute that might also need to be included at some stage (I've coded them all).

**This is what I need help with**

- Can someone advise how I identify the p-value?
- And suggest how I go about identifying if there's any correlation between my variables and the scores? Do I just keep doing the independent t-test but change the va

Thanks!
