Question

A set of n = 15 pairs of scores (X and Y values) produces a correlation of r = 0.40. If each of the X values is multiplied by 2 and the correlation is computed for the new scores, what value will be obtained for the new correlation?

Answer 1

Answer:

0.2

Step-by-step explanation:

the value obtained for new correlation will be $r=\frac{0.4}{2}=0.2$

correlation is a term which is used in statistic it is a statistical measure that indicates the range to which the two or more variables fluctuate together.

there are mainly two type of correlation that is positive correlation in which variables increase or decrease partially in negative correlation if one variable
