A scatterplot is produced to compare the size of a school building to the number of students at that school who play an instrume
nt. There are 12 data points, each representing a different school. The points are widely dispersed on the scatterplot without a pattern of grouping. Which statement could be true? There is no relationship between the size of a school building and the number of students who play an instrument because the scatterplot does not have a cluster.
As the size of a school building increases, the number of student musicians increases because the scatterplot has a cluster that increases from left to right.
As the size of a school building increases, the number of student musicians decreases because the scatterplot has a cluster that decreases from left to right.
The size of a school building is equal to the number of students who play an instrument because the scatterplot does not have a cluster.
There is not relationship between the size of a school building and the number of students who play an instrument because the scatterplot does not have a cluster.
Answer: Option A.
<u>Explanation:</u>
A scatterplot is a type of data display that shows the relationship between two variables. It makes use of the Cartesian coordinates to plot the values of the two variables for a set of data. This is used to show how much is one variable is affected by the other variable.
Since in the scatterplot which is being talked about in this question, it is scattered and is not clustered, this shows that there is no relationship between the size of the school and the number of the students who play instruments in the school.
