Please select the aspect of the Two-Sample Variance Procedures you would like practice with:
The Two-Sample Variance-Procedure is used to compare the variances of two populations. Using these procedures, you can calculate a confidence interval or test a hypothesis regarding the ratio of population variances. In order to use these procedures, the following assumption(s) must be met:
This assumption is in addition to the usual two assumptions that the sample is representative of the target population and that the sample values are independent.
If any of these assumptions are not met, then this is not the appropriate procedure to use. If the data are not Normally distributed, this is definitely not a good procedure to use.
