Assumes the populations are normally distributed and is extremely sensitive to departures from normality. The Levene and Brown-Forsythe tests are more robust against violations of the normality assumption than the F-test.

Most powerful test for symmetric, moderate-tailed, distributions.
Robust against many types of non-normality.
