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:
