How do F-tests work? Why do we analyze variances to test means? Web(Fixed factors simply refer to values that would be the same from one study to the next, such as race, gender, etc. Random factors are those that are selected from a larger possible set of values, such as a sampling of various areas along a stream from a larger set of possible watershed areas.) Move “Race” and “Gender” to the “Fixed Factors” box.

WebFeb 8, 2024 · The formula for ANOVA is F = variance caused by treatment/variance due to random chance. The ANOVA F value can tell you if there is a significant difference between the levels of the independent variable, when p < .05.
