Expert Solution
Step 1

Scatter Plot : Scatter plot is a graphical method used to find out the correlation between two quantitative variables . 

A scatter plot can show a positive relationship, a negative relationship, or no relationship.  It can determine as : 

  • If the points on the scatter plot seem to form a line that slants up from left to right, there is a positive relationship or positive correlation between the variables.

 

  • If the points on the scatter plot seem to form a line that slants down from left to right, there is a negative relationship or negative correlation between the variables.

 

  • If the points on the scatter plot seem to be scattered randomly, there is no relationship or no correlation between the variables.
