comparing means worksheet
John is interested in determining if frequency of exercise affects pulse rate. John randomly samples individuals at a local gym to ask if they will participate in his study. 55 individuals agree, and they are divided into three groups of exercisers: 1 = high frequency, 2 = moderate frequency, 3 = low frequency. Next, John measures their pulse after their workout. Do pulse rates differ among individuals who exercise with high frequency versus those who exercise moderately versus those who exercise with low frequency?
Note: Make sure you adjust the data so that there are three exercise variables (one for each level).
Conduct a one-way ANOVA to investigate the relationship between exercise frequency (Exercise) and pulse rate (Pulse1). Conduct Tukeyâ€™s HSD post hoc tests, if necessary. On the output, identify the following:
a. F ratio for the group effect
b. Sums of squares for the exercise effect
c. Mean for moderate exercisers
d. P value for exercise effect
