Graduation rate is one measure used to compare colleges in national publications. One such publication compared semester tuition against graduation rate, defined as the percentage of students who graduate within four years. The value of r for the scatterplot is 0.856.
A graph titled College comparisons has semester tuition (thousands of dollars) on the x-axis, and 4-year graduation rate (percentage) on the y-axis. Points are grouped together in a line with positive slope.

How would the correlation change if the graduation rate was plotted on the x-axis and tuition plotted on the y-axis?

The correlation would stay the same.
The correlation would stay positive and increase.
The correlation would stay positive and decrease.
The correlation would be negative, rather than positive.

The correlation change if the graduation rate was plotted on the x-axis and tuition plotted one the y-axis is option (A) The correlation would stay the same

What is Scatterplot ?

A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data.

What is Correlation?

It is a measure of the extent to which two variables are related.

Given,

A graph titled College comparisons has semester tuition (thousands of dollars) on the x-axis, and 4-year graduation rate (percentage) on the y-axis.

The value of the r for the scatterplot = 0.856

Here r is positive value therefore the data lies on a perfectly straight line with a positive slope

Therefore the correlation would stay the same

Hence, The correlation change if the graduation rate was plotted on the x-axis and tuition plotted one the y-axis is option (A) The correlation would stay the same
