Question

For a given data set, the equation of For a given data set, the equation of the least squares regression line will always pass throughthe least squares regression line will always pass through

Answer 1

Answer:

For a given data set , the equation of the least squares regression line will always passes through the point (x,y)

Step-by-step explanation:

For a given data set , the equation of the least squares regression line will always passes through the point (x,y)

For :

• The least-squares regression line equation always passes through the point (x, y).
• The correlation "r"  is the strength in relationship of a  straight-line
• The square of the correlation,that is $r^2$ , is the fraction of the variation in the values of y that is given by the least -squares regression of y changes on x.
