17.8.4 (PSS) One-Way ANOVA

Use this feature to determine the power of a one-way ANOVA test given the sample size or the sample size required to obtain a specified power for one-way ANOVA.

Generally speaking, Power and Sample Size tools can be used in two ways: sample-size estimation and power computation. The former can be used to determine the size of the sample to ensure a certain power when you are designing an experiment. The latter can be used to estimate the accuracy of the result after you have conducted an experiment on a specific number of samples.

To perform a Power and Sample Size for One-Way ANOVA:

  1. Select Statistics: Power and Sample Size: (PSS) One-Way ANOVA. This menu command opens the PSS_ ANOVA1 dialog box.
  2. From the Calculate list, choose Power or Sample Size, then choose your remaining options.
  3. Upon clicking OK, an analysis report sheet is generated.
