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?

Question

There is no relationship between the number of hours that students study and their test scores because the scatterplot does not have a cluster.
As the number of hours of studying increases, test scores decrease because the scatterplot has a cluster that increases from left to right.
As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.
The number of hours that students study is equal to the test scores because the scatterplot does not show a cluster.

Answer 1

The correct statement is:

As the number of hours of studying increases, test scores increase because the scatterplot has a cluster that increases from left to right.

This statement accurately reflects the positive correlation indicated by the scatterplot, where an increase in study hours is associated with an increase in test scores.
