Question
The two regression lines become identical if the correlation coefficient is
ans. 0
±1
2
none
Solution
The two regression lines become identical if the correlation coefficient is ±1. This is because a correlation coefficient of ±1 indicates a perfect linear relationship between the two variables. In this case, all the data points lie exactly on a straight line, and thus the regression lines predicting Y from X and X from Y are the same.

Suppose the correlation between two variables (x, y) in a data set is determined to be r = 0.63, What must be true about the slope, b, of the least-squares line estimated for the same set of data? The slope b is always equal to the square of the correlation r. The slope will also be a value between −1 and 1. The slope will have the same sign as the correlation. The slope will have the opposite sign as the correlation
If two variables are uncorrelated then regression lines are(a) Parallel(b) Perpendicular(c) Coincident(d) Inclined at 45 0
What can we say about the relationship between the correlation r and the slope b of the least-squares line for the same set of data? Both r and b always have values between −1 and 1. r is always larger than b. The slope b is always equal to the square of the correlation r. r and b have the same sign (+ or −). b is always larger than r.
