10.96 Improving employee evaluations Each of a random sample of 10 customer service representatives from a large department store chain answers a questionnaire about how they respond to various customer complaints.

Based on the responses, a summary score measures how positively the employees react to complaints. This is measured both before and after employees undergo an intensive training course designed to improve such scores. A report about the study states, “The mean was significantly higher after taking the training course [t = 3.40 1df = 92, P@value 6 0.05]. ” Explain how to interpret this to someone who has never studied statistics.

What else should have been reported to make this more informative?
