Suppose we have 6 months data of demand and forecast of any product. Perform f test to determine whether we can reject the null hypothesis at a 1 level of significance. Below you can find the study hours of 6 female students and 5 male students.
Go to data in the menu bar and select data analysis.
Click f test two sample for variances and then click ok step 3. Below are the steps where the f test formula is used to the null hypothesis that the variances of two populations are equal. Perform f test to determine whether we can reject the null hypothesis at a 1 level of significance. For example if you typed.
