finding out the relationship watch

1. Hi

I am trying to analyse my data for my dissertation. Its about exlicit correction. The learners were given a test and after 6 hours of teaching they were given the same test again. I need to see if there is a strong relationship between explicit correction and learning. I have been trying for days to work out this using pearson's correlation coefficient..but no luck!
Test one score were out of 24

8, 9, 8, 9, 6, 10, 7, 6

Test two

15, 13, 13, 15, 10, 16, 11, 10

Can anyone give me any advice? I am really stuck..maybe I have totally got it wrong
2. Just to clarify, when you say pearson's correlation coefficient, you do mean the PMCC? r= Sxy / root(Sxx*Syy)
Were you told to use this?

Is test two after the 6 hours of teaching?

Hi thanks for your reply. test two is after 6 hours of teaching...I do mean PMCC..but I have not been given further information..I chose this method myself..
4. Is a paired t-test more appropriate? Have you studied this?
Since the learners have been tested twice and you're looking at the before and after affect?
