When all the points fall on the regression line, the value of the correlation coefficient is 1.0 or -1.0.
According to the statement
we have to explain and tell about the value of correlation coefficient when all the points fall on the regression line.
So, For this purpose, we know that the
The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables.
And according to the statement,
If all of the data points fell on the line, there would be a perfect correlation between the x and y data points.
And due to this there were to be a perfect correlation, the correlation coefficient, r, would have a value of 1.0 or -1.0.
So, When all the points fall on the regression line, the value of the correlation coefficient is 1.0 or -1.0.
