A regression line using 25 observations produced SSR = 118.68 and SSE = 56.32. What was the standard error of estimate?
A) 2.2716
B) 2.1788
C) 1.5648
D) 1.5009

Question

Quizplus · Accepted Answer

The standard error of estimate (SE) can be calculated as:
SE = sqrt(SSE / (n-2))
where n is the number of observations.
Substituting the given values,
SE = sqrt(56.32 / (25-2))
SE = sqrt(2.7357)
SE = 1.6548
Therefore, the closest choice is C) 1.5648.
