Question

In testing the validity of a multiple regression model, a large value of the F-test statistic indicates that:

	a.	most of the variation in the independent variables is explained by the variation in y
	b.	the model provides a poor fit
	c.	most of the variation in y is explained by the regression equation and the model provides a poor fit
	d.	most of the variation in y is explained by the regression equation
	e.	most of the variation in y is unexplained by the regression equation

Answer 1

option d is right

In testing the validity of a multiple regression model, a large value of the F-test statistic indicates that: most of the variation in y is explained by the regression equation

The F-test of overall significance indicates whether your multiple regression model provides a better fit to the data than a model that contains no independent variables.

and large value of F test statistic indicates that most of the variation in y is explained by the regression equation
