Question

Jerry wanted to see if listening to music would make the basketball players make more baskets. On day one,

he didn't play any music and counted how many baskets they would make in ten minutes. On day two, he
played rap music and counted the number of baskets made, and on day three, he played classical music and
counted the number of baskets again. He allowed all players to shoot baskets each day for two minutes.

b. What is the independent variable?
c. What is the dependent variable?
d. What variables are controlled?
e. Is this a controlled experiment? Why or Why not?
f. What type of data is being recorded?

Answer 1

b. The independent variable in this experiment is the type of music played (no music, rap music, classical music).

c. The dependent variable in this experiment is the number of baskets made by the basketball players.

d. The variables that are controlled in this experiment are the duration of time for shooting baskets (two minutes) and the same group of basketball players participating each day.

e. Yes, this is a controlled experiment. It is controlled because the researcher is manipulating the independent variable (type of music played) while keeping other variables constant (same duration of time, same group of players). By controlling these variables, the researcher can determine if there is a causal relationship between the type of music and the number of baskets made.

f. The data being recorded is quantitative data, specifically the number of baskets made by the basketball players.
