This is an essential part of the Analysis of Variance (ANOVA). One of the assumptions of any method that pools sample variances is that the samples arise from populations with homogeneous variances. The F-test value that is returned by the LINEST function differs from the F-test value that is returned by the FTEST function. We calculate whether Null Hypothesis (H0) for the given set of data is TRUE or not. For un-statistical background people, it becomes difficult to understand and measure different observations. We will be using the scores of students across two different subjects to depict example on F test in Excel, Which is shown below. In the Data Analysis dialog box, we will click on f-test two samples … F-Test can be performed on one or more than one set of data in Excel. 2. After that, another dialog box of F-Test will appear. LINEST returns the F statistic, whereas FTEST returns the probability. We calculate whether Null Hypothesis (H0) for the given set of data is TRUE or not. Now select.
