Note that the p-value approach and the F critical value approach will always lead to the same conclusion.As the article suggests, today we will learn how to add Analysis ToolPak in Excel For Mac and Windows PCs. In this case, since the overall F value is greater than the F critical value we would reject the null hypothesis. Note: You could also compare the overall F value to the F critical value to determine whether you should reject or fail to reject the null hypothesis. This means that the three studying methods do not all lead to the same average exam scores. 05, we reject the null hypothesis of the one-way ANOVA and conclude that we have sufficient evidence to say that not all of the group means are equal. Recall that a one-way ANOVA uses the following null and alternative hypotheses: The most important value in this table is the p-value, which turns out to be 0.002266. F crit: The F critical value that corresponds to α =.P-value: The p-value corresponding to the overall F-value.F: The overall F-value, calculated as MS Between / MS Within.MS: The mean sum of squares, calculated as SS / df.df: The degrees of freedom, calculated as #groups-1 for df Between and #observations – #groups for df Within.SS: The sum of squares for each source of variation.Source of Variation: The variation being measured (either between groups or within groups).To determine if the differences in the group means are statistically significant we must refer to the ANOVA table. This table provides us with several useful summary statistics for each group used in the ANOVA.įrom this table we can see that the students who used Method 3 had the highest average exam score (86.7) but they also had the highest variance in exam scores (13.56667). Variance: The variance of the values in each group.Average: The average value in each group.Sum: The sum of the values in each group.Count: The number of observations in each group.Here’s how to interpret the values in each table: There are two tables that are shown in the output: SUMMARY and ANOVA. Once you click OK, the results of the one-way ANOVA will appear: In the new window that appears, enter the following information: Select Anova: Single Factor, then click OK. Once you click this, a new window will appear.

Suppose the teacher wants to perform a one-way ANOVA to determine if the mean scores are the same across all three groups. The following screenshot shows the scores of the students based on the method they used: Suppose a teacher randomly assigns 30 students in her class to use one of three studying methods to prepare for an exam. Example: How to Interpret ANOVA Results in Excel The following example provides a complete guide on how to interpret the results of a one-way ANOVA in Excel. An one-way ANOVA is used to determine whether or not there is a statistically significant difference between the means of three or more independent groups.
