Explanation

From the mean of both male and female, we have witnessed that the heart rates of male and female are different at different with or without activity. Female have a generally higher heart rate compared to the male heart rate the difference being 1.4 while resting and 0.9 after exercising.

Male heart rates have a wider variance compared to that of the female. The inconsistency more pronounced when looking at heart rates after exercise.
