We cannot reject the null hypothesis that the AB interaction had a statistically significant effect on the dependent variable. For the AB interaction, the P-value (0.88) is bigger than the significance level (0.05), so.We cannot reject the null hypothesis that Factor B had a statistically significant effect on the dependent variable. For Factor B, the P-value (0.09) is bigger than the significance level (0.05), so.We reject the null hypothesis and conclude that Factor A had a statistically significant effect on the dependent variable. For Factor A, the P-value (0.03) is smaller than the significance level (0.05), so.Than the significance level, we accept the null hypothesis for a treatment effect when it is smaller, we reject it. The P-value (shown in the last column of the ANOVA table) is the probability that an F statistic would be more extreme (bigger) than theį ratio shown in the table, assuming the null hypothesis is true. The null hypothesis for the AB interaction states that Factor AĪnd Factor B did not interact to affect the dependent variable. The null hypothesis for Factor B states that Factor B had no effect of the The null hypothesis for Factor A states that Factor A had no effect of the

In a two-factor, full factorial experiment, analysis of variance tests a How strong is the effect of independent variables on the dependent variable?Īnswers to both questions can be found in the ANOVA summary table.Do the independent variables have a significant effect on the dependent variable?.Recall that the researcher undertook this study to answer two questions: If you see Data Analysis in the Analysis section, you're good. To determine whether you have the Analysis ToolPak, click the Data tab in the main Excel menu. Which may or may not be already installed on your copy of Excel.
To access the analysis of variance functions in Excel, you need a free Microsoft add-in called the Analysis ToolPak, Required to solve the same problem that we will solve in this lesson with Excel. Two-Factor Analysis of Variance: Examples. Note: If you're curious about what goes on "behind the scenes" with Excel, read the previous lesson:

We'll explain how to conduct the analysis and how to interpret results for In this lesson, we demonstrate how to use Excel to conduct analysis of variance on results from a balanced, two-factor, full-factorial experiment.
