Which phrase best describes a scatter plot in which the variables are correlated with r = 0.79?

a.) weak negative association
b.) weak positive association
c.) strong negative association
d.) strong positive association

D.) strong positive association

Step-by-step explanation:

The given correlation coefficient

Since its polarity is positive then it must represent a positive association.

We know that if the r value is closer to +1 or -1 then it tells that there is a stronger linear relationship between the two variables.

Also it lies between 0.5 to 1 i.e. 0.5 < 0.79 < 1, therefore it must represent a strong positive association between the two variables.

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis
