A researcher computes an analysis of regression with 1 and 18 degrees of freedom.If F = 3.05,then the decision will be that X is a significant predictor of variation in Y.

Question

Quizplus · Accepted Answer

To determine if X is a significant predictor of variation in Y, we compare the computed F value (3.05) to the critical F value at a certain significance level (usually 0.05) for 1 and 18 degrees of freedom. Without knowing the critical F value or the significance level used, we cannot conclude that X is a significant predictor solely based on the F value of 3.05.
