WebANOVA/MANOVA). The F distribution is a ratio of two Chi-square distributions, and a specific F distribution is denoted by the degrees of freedom for the numerator Chi-square and the degrees of freedom for the denominator Chi-square. An example of the F(10,10) distribution is shown in the animation above. When WebMay 27, 2024 · A test statistic is one component of a significance test. It is used to determine how unusual your result is assuming the null hypothesis is true. For example, let’s say you flip a coin three ...
