4. Most sports injuries are immediate and obvious, like a broken leg. However, some can be more subtle, like the neurological damage may occur when soccer players repeatedly head a soccer ball. To examine long-term effects of repeated heading, Downs and Abwender (2002) examined two different age groups of soccer players and swimmers. The dependent variable was performance on a conceptual thinking task. Following are hypothetical data, similar to the research results.

4. Most sports injuries are immediate and obvious, like a broken leg. However, some can be more subtle, like the neurological damage may occur when soccer players repeatedly head a soccer ball. To examine long-term effects of repeated heading, Downs and Abwender (2002) examined two different age groups of soccer players and swimmers. The dependent variable was performance on a conceptual thinking task. Following are hypothetical data, similar to the research results. Soccer, Older n = 20 Soccer, College n = 20 M= 9 M= 4 T= 180 T= 80 SS = 380 SS = 390 Swimming, College n = 20 M= 9 Swimming, Older n = 20 M= 8 T= 180 T= 160 SS = 350 SS= 400 a. Using the 5 steps of hypothesis testing, do these data indicate any significant differences for the conceptual thinking task? b. Compute n² for each F test.
