Question

what would the independent variable be in this experiment, and where would it go in the hypothesis?
how fast the students run after the if
how fast the students run after the then
the volume of the music after the if
the volume of the music after the then

Explanation:

. In a hypothesis (usually in an "If...then..." format), the independent variable comes after the "if" because it is the condition that is being tested. Here, the volume of the music is what is likely being manipulated (the independent variable), so it would go after the "if" in the hypothesis.

Answer:

the volume of the music after the if
