Answer:
(4) Hours studying compared to test score
Explanation:
Bivariate means two (bi-) variables. That means we must test for two variables for the data. Let’s analyze each of the choices.
(1) Shoe sizes of a tennis team: We are only measuring one variable: shoe sizes, so let’s eliminate this.
(2) Goals scored in soccer game: We are only measuring one variable: goals scored, so let’s eliminate this.
(3) Calories consumed in one day: We are only measuring one variable: calories consumed, so let’s eliminate this.
(4) Hours studying compared to test score: Here, we must measure the hours studying and the test score for the data, which are two variables. Therefore, this is our answer.
I hope this helps! :)
