Question

what type of correlation does the data set display?

x	y
5	13
7	-6
9	11
11	8

Explanation:

Step1: Observe data trend

As x - values increase from 2 to 5, y - values increase from 5 to 13. But when x increases from 5 to 7, y decreases from 13 to - 6. Then as x increases from 7 to 9, y increases from - 6 to 11, and from 9 to 11, y decreases from 11 to 8.

Step2: Determine correlation type

There is no consistent upward or downward trend between x and y values.

Answer:

No correlation
