If I ride my bike to school instead of walking then I will get to school faster what is the dependent variable?

A. The location of the school

B. Riding a bike or walking

C. How fast you get to school

D. The type of bike

The answer to this question is C. How fast you get to school

Explanation:

In this situation, the factor that is being tested is the time it takes to go to school. Also, this is tested by controlling the way to go to school (walking vs riding a bike). In experiments, the main factor studied is known as the dependent variable. This means in this situation the dependent variable is how fast you get to school.

Moreover, this variable is dependent because it is modified by the variable controlled by the researcher, which is the way to go to school. This means, how fast you get to school depends on other factors including if you walk or go by bike. According to this, the dependent variable is how fast you get to school.
