If we assume that the three variables are centered their means were brought to 0the what is the correlation coefficient r of a linear regression coefficient found in many textbooks could be written as follows:. If we substitute all SCP in the numerator accordingly and then simplify we'll what is the correlation coefficient r that the numerator is proportional to the quantity.

Consider the following fictional scenario. In a given what is the correlation coefficient r, people get fatter as they get older. As a consequence, their doctors recommend that they exercise more. So older what is the correlation coefficient r fatter people exercise more than young, skinny ones. The correlation between weight and exercise would be positive simple correlation. But if you adjust for age, you would find that those who exercise have lower weight than those that do not exercise for a given age.
