Quizplus · Accepted Answer

The regression coefficient and correlation coefficient of two variables will be the same if their standard deviations are the same. This is because both coefficients measure the relationship between variables, and having the same standard deviation implies a direct and proportional relationship, which is a condition for these coefficients to be equal.
