Question

Which table shows a negative correlation?

Answer 1

If we graph the x - y values in a scatter plot and draw a line of best fit, we can easily see the solution.

Negative correlation means y decreases as x increases, or a negative sloping line.

Attached is the graphs of all the 4 choices. Clearly, the 4th table shows negative correlation.

ANSWER: Last table (4th table) shows negative correlation

Answer 2

The correct answer is:

The last table.

Explanation:

A negative correlation means that as x increases, y decreases.

In the first table, as x increases, y increases; this is a positive correlation.

In the second table, as x increases, y stays constant. This is not a negative correlation.

In the third table, as x increases, y first decreases, then increases. This is not a negative correlation.

In the last table, as x increases, y decreases; this is a negative correlation.
