For the table​ below, make a scatter plot of the data. Describe the type of correlation the scatter plot shows.

Question

Jeans Sales
Average Price​ ($)
21
28
36
40
Number Sold
127
115
85
65

Answer 1

To create a scatter plot, we plot the average price ($21, $28, $36, $40) on the x-axis and the number sold (127, 115, 85, 65) on the y-axis.

The scatter plot may look like this:

|
110| o
|
100| o
|
90| o
|
80| o
|
------------------------
20 25 30 35 40

Based on the scatter plot, we can observe a negative correlation between the average price and the number of jeans sold. As the average price increases, the number of jeans sold decreases. Therefore, there is a negative correlation between the average price and the number sold.
