The **null** **hypothesis** will be that all population means are equal, the alternative **hypothesis** is that at least one mean is different. In 1918, Ronald Fisher developed a test ed the analysis of variance. If you set the Type one error to be .05, and you had several s, each time you tested a mean against another there would be a .05 probability of having a type one error rate.

The Test Statistic F = the variance between samples / the variance within samples. (sample is also ed treatment or factor) To look up the F critical value we need: the numerator degrees of freedom (k-1) the denominator degrees of freedom k(n-1) Where "k" is the number of different samples (also ed treatments, or factors) "n" is the number of items within each sample.
