Question

Suppose you hear that conscientious people are more likely to get regular health checkups. Which of the following correlations between conscientiousness and getting checkups would probably support this claim?
A. R = .03
B. R = .45
C. R = −.35
D. R = −1.0

Answer 1

Answer: B. R= 0.45

Explanation: 'r' usually referred to as the correlation coefficient used to measure the strength and direction of the statistical relationship or correlation between two linear variables. It ranges between -1 to 1

The strength of a relationship is measured by its closeness to 1 or -1, while 0 indicates no correlation.

A positive r value shows a positive relationship that is increase on one variable leads to increase in the other while a negative r value shows a negative correlation, that is increase in one variable leads to decrease in the other and vice versa.

r value close to -1 indicates the strength of a negative correlation while r value close to 1 indicates the strength of a positive correlation.

In the scenario above, the most probable r value to indicate positive relationship between consentiousness and regular checkup is 0.45.
