A scatterplot is produced to compare the number of hours that students study to their test scores. There are 25 data points, each representing a different student. The scatterplot shows a grouping of points rising from left to right. Which statement could be true?
Answer
A
There is no relationship between the number of hours that students study and their test scores because the scatterplot does not have a cluster.
B
The number of hours that students study is equal to the test scores because the scatterplot does not show a cluster.
C
As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.
D
As the number of hours of studying increases, test scores decrease because the scatterplot has a cluster that increases from left to right.
