In F sampling distribution F is calculated by dividing a variance of one sample by the other sample’s variance.įor the right-tailed test and two-tailed test, make sure to keep the highest variance as the numerator and the lowest variance as the denominator. The selection of one or two-tailed tests depends upon the problem. Whereas two-tailed, the area of rejection is in two directions. One-tailed hypothesis is a test of hypothesis where the area of rejection is only in one direction. ![]() Hypothesis testingĪ tailed hypothesis is an assumption about a population parameter. F test is to find out whether the two independent estimates of population variance differ significantly (or) to find out whether the two samples drawn from the normal population having the same variance. reject the null hypothesis If the test statistic falls in the critical region. Finally, draw the statistical conclusion.Compute the critical F value from F table.Calculate the F statistic, choose the highest variance in the numerator and lowest variance in the denominator with a degrees of freedom (n-1).Choose the test: Note down the independent variables and dependent variable and also assume the samples are normally distributed.It also indicates a linear relationship between dependent variable and at least one of the independent variable. F-test for linear regression model is to tests any of the independent variables in a multiple linear regression are significant or not. ![]() While ANOVA uses to test the equality of means.
