Question

1. in an experiment to determine the effects of listening to loud music on test scores, what would the x-axis label be?

a) type of music
b) test score
c) grade in class
d) volume of music

Explanation:

In an experiment, the x-axis represents the independent variable (the variable being manipulated to test its effect). Here, the experiment tests how loud music affects test scores, so the manipulated variable related to "loud music" is its volume. Test score is the dependent variable (y-axis), type of music is not the focus (the experiment specifies loud music), and class grade is irrelevant.

Answer:

d) Volume of music
