Question
An aerobics teacher believed that physical conditioning is an essential factor in the ability to perform skills, even if the skill does not require strength
An aerobics teacher believed that physical conditioning is an essential factor in the ability to perform skills, even if the skill does not require strength or endurance. To test this hypothesis, she selected ten high BMI (body mass index) women enrolled in her aerobics course. Before the first class, she tested them on a button-sorting task. After an entire semester of regular exercise, she tested the women on the same button-sorting task. Scores represent the number of seconds required to sort the buttons. Analyze the data with a nonparametric test and comment on the results.
