A research report concludes that there are significant differences among treatments, with “F(2, 24) = 8.62, p < .01.” If the same number of participants was used in all of the treatment conditions, then how many individuals were in each treatment?

Answer #1
  • There were 9 individuals in each treatment.Analysis of Variance (ANOVA) is a statistical method used to test differences between two or more means. It may seem odd that the technique is called "Analysis of Variance" rather than "Analysis of Means." The F-Statistic: Variation Between Sample Means / Variation Within the Samples. The F-statistic is the test statistic for F-tests. In general, an F-statistic is a ratio of two quantities that are expected to be roughly equal under the null hypothesis, which produces an F-statistic of approximately 1.
