Again, I'm struggling with articulating my response. Any reply will be helpful in guiding me!

Based on your results, determine whether the data provide evidence for a valid effect.

This is regarding a statistical analysis for a two-sample t-test of the following data set:

Group A Confidence ratings (on a scale of one to ten): 7 , 10, 9, 10, 8, 5, 10, 10, 1, 10, 5, 6, 7, 6, 4, 5, 10

Group B Confidence ratings (on a scale of one to ten): 10, 5, 5, 10, 7, 6, 10, 9, 3, 6, 4 , 10, 10, 10, 3, 7, 8

Group A mean: 7.24 Standard deviation: 2.705

Group B mean: 7.24 Standard deviation: 2.611

I'm not sure if effect size or correlation coefficient is something to include in this answer?
