Beckman hypothesized that experience playing video games would improve a person's spatial skills. Each participant's spatial skills were measured. Participants then played video games for two hours and their spatial skills were measured again at the end ofthe game. The number of correct spatial problems was recorded for each participant. Analyze the following data, state your null hypothesis, and report your critical value using α = .05. Interpret your results. sD= 2.8 Before: 7,5,8,3,4,5 M = 5.33 After: 10,6,5,5,7,9 M = 7
