Constructing Scatterplots — Quiz

Question 4 • Mathematics 8

Kevin went fishing and is using a scatterplot to analyze the relationship between the weight of each of the fish he caught in pounds and in kilograms. He uses the weight in pounds as the independent variable and the weight in kilograms as the dependent variable. Which statement is correct?

Answer
A
The points on the scatterplot will go up from left to right because as the weight in pounds increases, the weight in kilograms increases.
B
The points on the scatterplot will go down from left to right because as the weight in pounds increases, the weight in kilograms increases.
C
The points on the scatterplot will go up from left to right because as the weight in pounds increases, the weight in kilograms decreases.
D
The points on the scatterplot will go down from left to right because as the weight in pounds increases, the weight in kilograms decreases.

Explanation

Pounds and kilograms measure the same quantity, and kilograms increase as pounds increase. Since pounds are on the horizontal axis and kilograms are on the vertical axis, larger pound values pair with larger kilogram values, so the points rise from left to right. Choice A states this positive relationship.
