One-way analysis of variance is part of the family of tests known as analysis of variance (ANOVA). Typically, it is used to analyze experimental designs in which only one …
Abstract. So far in this book, you have learned how to test for the difference within one group of data between the mean of the group and the hypothesized population mean for the data using either the 95 % confidence interval about the mean (Chap. 3 of this book) or the one-group t-test of the mean (Chap. 4 …

One-way analysis of variance (ANOVA) is the natural generalization of the two-sample t-test to more than two groups. Suppose that we have a factor A with a levels. We select independent samples from each of these a populations, where n i is the size of the sample from population i .
One-way analysis of variance tells me that a difference exists but does not allow me to compare population means to one another to determine where the difference is. That task requires further analysis, such as the Scheffé test. BOB’S BASICS To use one-way ANOVA, the following conditions must be satisfied: The populations of interest must be normally distributed. The samples must be
