Question

A researcher in Alaska measured the age (in months) and the weight (in pounds) of a random sample of adolescent moose. When the least-squares regression analysis was performed, the correlation was 0.59. Which of the following is the correct way to label the correlation?
a. 0.59 months per pound
b. 0.59 pounds per month
c. 0.59
d. 0.59 months times pounds
e. 0.59 month pounds

Answer 1

Answer:

c. 0.59

Explanation:

Correlation co-efficient  refers to a statistical measure that computes the strength of a relationship between two variables. It does not have a unit like meter per second or months per pound. A correlation co-efficient of 1 means that there is a strong and positive relationship or direct relationship, while a negative correlation means an inverse relationship.
