Question

makayla wants to determine if the length of the string affects the number of times a pendulum will swing back and forth in 10 seconds. what is the independent variable (iv) and the dependent variable (dv)? iv: pendulum dv: number of seconds iv: length of string dv: times the pendulum swings iv: times the pendulum swings dv: number of seconds iv: length of string dv: number of seconds

Explanation:

The independent variable is what is changed in an experiment. Here, MaKayla changes the length of the string. The dependent variable is what is measured as a result of the change in the independent variable. She measures the number of times the pendulum swings in 10 seconds. So the length of the string is the independent variable and the number of times the pendulum swings is the dependent variable.

Answer:

IV: length of string
DV: times the pendulum swings
