A research study wishes to examine the mean resting heart rate for 16 individuals among four different groups of exercises (evenly distributed to 4 individuals per group). What type of test statistic do you need to run for this type of analysis?

The test statistic here will be F-statistic with degrees of freedom in numerator as: = k-1 = 4-1 = 3 (number of categories minus 1), and in denominator as n-k = 16-4 = 12
