A researcher computes an analysis of regression with 1 and 18 degrees of freedom.If F = 4.05,then the decision will be that X is a significant predictor of variation in Y.

Question

Quizplus · Accepted Answer

The significance of the predictor depends on the critical value of F at a chosen significance level (e.g., 0.05). For 1 and 18 degrees of freedom, the critical F value is approximately 4.41 at the 0.05 level. Since 4.05 is less than 4.41, X is not a significant predictor.
