Comment: Central tendency: Females > Males (Females have higher typical resting heart rates).
Variation: Females have slightly more variation.
Shape: Male distribution is smoother and symmetric, while the female distribution is more uneven.

qqnorm(Female$Beats)
Comments:
Male heart rate data is approximately normally distributed, with only minor tail deviations.
Female heart rate data shows more variation and positive skewness, driven by several higher heart rate values.
This matches the earlier histogram findings where females had more spread and higher extreme heart rates compared to males.
Females generally have higher typical resting heart rates compared to males.
Female heart rates are more spread out, suggesting more diversity in heart rate patterns.
Males: The box is symmetric, showing a fairly normal, balanced distribution.
Females: The box leans slightly upward (longer top whisker), indicating a mild positive skew with a few individuals having very high heart rates.
SUMMARY:
