Question

Megan collected data on the number of steps taken per day and the number of kilometers walked per day. She then calculated the equation for the line of best fit and the correlation coefficient as r = 0.92. What is the relationship between the number of steps and kilometers walked per day?

a) Positive correlation
b) Negative correlation
c) No correlation
d) Perfect correlation

Answer 1

The relationship between the number of steps and kilometers walked per day is a positive correlation.

Step-by-step explanation:

The correlation coefficient, r, measures the strength of the linear association between the number of steps and kilometers walked per day. In this case, the correlation coefficient is r = 0.92, which indicates a positive correlation. This means that as the number of steps taken per day increases, the number of kilometers walked per day also tends to increase, and vice versa.
