Question

This table presents a set of ordered pairs, showing the relationship between two variables, where the first column contains values ranging from -1 to 4 and the second column lists corresponding negative values.
x y
−1
−10

0 −8

1 −7

2 −5

3 −3

4 −1

Use the data table to create a scatter plot. Based on the data, which of the following choices would be the best estimated correlation coefficient?

(1 point)
Responses

−1

negative 1 - no response given

0.98
0.98 - no response given

−0.90

negative 0 point 9 0 - no response given

−0.98

negative 0 point 9 8 - incorrect
Incorrect

Answer 1

0.98

The points lie almost exactly on a straight line with a positive slope (y increases as x increases). The Pearson r is very close to +1 (about 0.996), so 0.98 is the best choice.
