Significance F

Statistically speaking, the significance F is the probability that the null hypothesis in our regression model cannot be rejected. In other words, it indicates the probability that all the coefficients in our regression output are actually zero!

What does significance F mean in Anova?

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

What does a high F significance mean?

A large F-value means the between-group variation is larger than your within-group variation. This can be interpreted to mean there is a statistically significant difference in your group means.

Is significance F the same as the p-value?

The F value is used to calculate the P value - whether or not the F value is significant or not depends on the degrees of freedom. Whether or not it is above or below 0.05 does not directly indicate significance.
