Question

The scatter plot shows the relationship between the test scores of a group of students and the number of hours they spend on social media in a week.

Part A: What is the group of points labeled A called? What is the point labeled B called? Give a possible reason for the presence of point B.
Part B: Describe the association between a student’s test scores and the number of hours spent on social media

Answer 1

Part A:

The group of points labelled A are called CLUSTERS. The points in this group form a distinct group.
The point labelled B is called OUTLIER. This point doesn't seem to 'join' in with the clusters

Possible reason for point B is there are students who still managed high score in the test while spending large amount of time on social media

PART B:

The relationship is a negative correlation. The longer a student spent time on social media, the lower their score in a test.
