We want to know whether scores on a test improve after a training class in a sample of employees. The scores of the same set of employees were measured before and after the training class. We ran an independent samples t-test and got a p-value of .49. What is the correct interpretation? The training class did not significantly improve scores The groups are not independent, so we should run a paired t-test The data is not normally distributed, so we should run a non-parametric test The training class significantly improved scores
