Anova two factor with replication in Excel

ANOVA, short for Analysis of Variance, is a vital statistical tool for assessing variance between groups. In this Excel tutorial, you’ll learn how to conduct a Two-Factor ANOVA with replication test. Follow these steps to enhance your data analysis capabilities.

Data preparation

Start by preparing your data table. Here’s an example:

Data analysis

Navigate to the “Data” tab on the Excel ribbon.

Look for the “Data Analysis” button. If it’s not visible, you’ll need to install the “Analysis ToolPak” add-in.

In the dialog box, specify the “Input Range,” which should include only the numeric data from your table. For example, in my sheet, it’s defined as $A$1:$F$5. Ensure your data table has labels.

In each example or group of students, if you have multiple samples, specify the number of replicates.

Leave the “Alpha” value at its default setting of 0.05.
