Question 10 • Pre-Algebra B

Which describes a correct way to construct a scatterplot?

Answer
A
When analyzing the number of home runs that a baseball player hit over several seasons, the season is the independent variable.
B
When analyzing the number of umbrellas that are sold during days with varying amounts of rain, the number of umbrellas that are sold is the independent variable.
C
When analyzing the number of registered voters by age, age is the dependent variable.
D
When analyzing the number of students that ride the school bus each day of the week, the day is the dependent variable.

Explanation

In a scatterplot, the independent variable is the factor used to explain or predict changes in the dependent variable. For home runs recorded over several seasons, season is the independent variable, and the number of home runs is the dependent variable. The other choices reverse this relationship: rainfall, age, and day of the week are the independent variables in those examples.
