Question

Given the following information for a set of X and Y scores:

   MX = 4, SSY = 95, SSX = 70, MY = 5, SP = 30, n = 7

What is the standard error of the estimate and what is it telling you?

2.28, the average difference between the predicted scores in the regression line. 2.75, the standard distance between the predicted scores and the regression line. 3.70, the distance between one data point and the scores in the regression line. 4.04, the average difference between the actual scores and the regression line.

Explanation / Answer

here SSE =(SSy-SP2 /SSx)=95-302/70=82.14

hence std errror of estimate =sqrt(SSE/(n-2))=sqrt(82.14/5)=4.05

4.04, the average difference between the actual scores and the regression line.
