Question
Which of the following data sets would most likely have a negative association and a correlation coefficient between 0 and -1?
a.) Swimsuit sales throughout the year Sunscreen sales throughout the year
b.) Steepness of the Appalachian Trail John's speed while hiking up the Appalachian Trail
c.) Number of miles driven by Paul Number of gallons of gas used by Paul's car
d.) Average Summer temperature in the United States Summer air-conditioning costs for homes in the United States
Solution
The data set that would most likely have a negative association and a correlation coefficient between 0 and -1 is:
b.) Steepness of the Appalachian Trail and John's speed while hiking up the Appalachian Trail
This is because as the steepness of the trail increases (independent variable), John's speed (dependent variable) would likely decrease. This is a negative association because an increase in one variable corresponds with a decrease in the other. The correlation coefficient would be between 0 and -1, indicating a negative correlation.
