Question

1. c.j wanted to see if listening to music would make the basketball players make more baskets. on day one, he didnt play any music and counted how many baskets they could make in 10 minutes. on day 2, he played rap music and counted the baskets, and on day 3, he played classical music and counted the baskets.

a. independent variable (iv):

b. dependent variable (dv):

c. control:

Explanation:

Part a

The independent variable is the factor that is manipulated in an experiment. Here, CJ is changing the type of music (or whether music is played) to see its effect on baskets made. So the independent variable is the type of music (or presence/absence of music).

The dependent variable is the factor that is measured and depends on the independent variable. In this experiment, the number of baskets made depends on the type of music played. So the dependent variable is the number of baskets made.

The control is the part of the experiment where the independent variable is not applied (or is at a baseline) to compare with the experimental groups. Here, day 1 when no music was played serves as the control to compare with the days when rap or classical music was played.

Answer:

Type of music (or presence/absence of music)
