Comparing Variance with the F-Test
Description
The F-test compares variance in two data sets or compares a sample variance with a population variance. It helps decide whether an indeterminate error can explain a difference in the values. In statistics, variance shows how spread out the data are.
The test assumes that the data set or sets are ...

Transcript
The F-test checks if the difference between two variances is too large to be explained by an indeterminate error. It compares the variance of a sample and that of a population or the variances of two samples.
The F-test is based on the null hypothesis, which states that the two variances compared are equal.
The te...
