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.
The correct option is A
