ANSUR II dataset

Show heights for women and men on same plot.

• A. Why is the data of men higher than the data of women?

  Because there are more male data than female data (because 1985 females and 4081 males).

• B. Why is the data of men more right than the data of women?

  Because men are taller. For a better comparison, the following chart with the same density is proposed.

Answer :

🚹 Mean of Women height = 162.84 cm
🚺 Mean of Men height = 175.62 cm
