F-Test for testing equality of variances of two normal populations Test conditions The populations are normal Samples have been drawn randomly Observations are independent; and There is no measurement error Ha may be one sided or two sided Test statistics = 1 2 2 2 1 1 and 2 1 d. f. 1 2 is the sample estimate for 1 2 2 2 is the sample estimate … The t-test and Basic Inference Principles The t-test is used as an example of the basic principles of statistical inference. One of the simplest situations for which we might design an experiment is the case of a nominal two-level explanatory variable and a quantitative outcome variable. Table6.1shows several examples.

The F-test is a parametric test that helps the researcher draw out an inference about the data that is drawn from a particular population. The F-test is called a parametric test because of the presence of parameters in the F- test. These parameters in the F-test are the mean and variance.

no effect on (the mean of) y". This test is rejected at the 1% level by the F test since the P-value is smaller than .01. It might seem predictable that this F test would reject, since we already rejected the null hypothesis that groups 1 and 2 have equal means using the t test on the Ix 2 coefficient. But the
