In linear regression, the t-statistic is useful for making inferences about the regression coefficients. The hypothesis test on coefficient i tests the null hypothesis that it is equal to zero – meaning the corresponding term is not significant – versus the alternate hypothesis that the coefficient...

The f test statistic formula is given below:F statistic for large samples: F = σ21σ22σ12σ22, where σ21σ12 is the variance of the first population and σ22σ22 is the variance of the second population.F statistic for small samples: F = s21s22s12s22, where s21s12 is the ...
The F-distribution contains all of the possible values for a test statistic. It is determined by the degrees of freedom and is always skewed right, meaning that all of the values are greater than zero. What does an F-test tell you? An F-test is a statistical method for comparing the ...
null hypothesis in this case is ,H0:and an appropriate alternate hypothesis is to be used. The F value is calculated asF =.Also the degrees of freedom are n-1 and m-1. This is then compared to the table value of F Statistic for the required confidence interval and degrees of freedom....

Looking back at the one-way ANOVA output, which statistic do we use for the between-group variance? The value we use is the adjusted mean square for Factor (Adj MS 14.540). The meaning of this number is not intuitive because it is the sum of the squared distances from the global mean...
