Question

A data set consists of the following pairs of data:
(2, 4), (4, 7), (5, 12)
Will the correlation coefficient for these data points be positive or negative?

Answer 1

yes, because as the x values increase 2, 4, 5 the corresponding y values also increase 4, 7, 12

if you plotted them on a number plane you would see then you could draw a line with a positive slope that is close to all 3 points

Answer 2

thank you
