Pl ! the scatter plot shows the relationship between the number of homework assignments turned in over a week and the test score for that same week: part a: what is the group of points labeled x called? what is the point labeled y called? give a possible reason for the presence of point y. part b: describe the association between a student’s test scores and the number of homework assignments submitted.

Part A

A scatter plot is a plot of points of two variables in the coordinate plane. A group of points that are close together in a scatter plot is called a cluster.

Thus, the group of points labelled X is called clusters.

A point that is far away from other points in a scatter plot is called an outlier.

Thus, the point labelled Y is called an outlier.

An outlier exists in a scatter plot when there exists an unusually low value or an unusually high value of data in the data set.

Part B

From the scatter plot, it can be seen that the cluster of points representing the relationship between the number of homework assignments turned in over a week and the test score for that same week rises from bottom left to top right.

This case of association is called a positive association.

What is the inequality?
