Question: Does your height effect the size of your shoe?

Explanatory Variable: Height

Response Variable: Size of shoe

I expect there will be a positive association because the taller someone is, it is more likely for them to have a bigger shoe size.

I will observe 10 males and 10 females and record their name, height, and shoe size.

My results were positive and reflect what I predicted. This shows that 77% of people's height reflects their shoe size. My "r" or correlation was .87. Since it is so close to one, it has a strong positive association.
