You are testing to see if the size of your feet is related to what size shoes you purchase.

Question

Size of your shoes:
Size of your feet:
Which is dependent

Answer 1

In the relationship between the size of your feet and the size of shoes you purchase, the size of your shoes is considered the dependent variable, while the size of your feet is the independent variable.

This is because the size of your shoes is largely determined by the size of your feet; thus, changes in the size of your feet will directly impact the size of shoes you need to buy.
