How to use Anova in Excel

Anova means Analysis of Variance. In this Excel tutorial, you will teach yourself how to perform Anova.

ANOVA is used to test for the significance of the difference between the means of two or more samples.

In order to be able to perform the analysis of variance, 3 conditions must be met:

  1. independent samples;
  2. from a normal population;
  3. homogeneity of variance.

Data preparation

Let’s start from preparing data table.

  • Organize your data into columns, with each column representing a group of data.
  • Label each column with a descriptive heading.
  • Make sure that each column contains an equal number of observations.

Here is an example:

Anova data table

Data analysis

Next go to the ribbon to the Data tab. Click Data Analysis button.

Data Analysis ribbon button

If you don’t have this button it means that you have to install Analysis ToolPak add-in.

Anova calculations

New dialog box appears. Click Anova: Single Factor option.

Anova Single Factor

Select Input Range which is your data table (only numbers). In my sheet it is $B$2:$F$6

In the Alpha box, enter the level of significance you want to use for the test. A common value is 0.05.

Note: If your data has headers, check the Labels in First Row check box.

Anova Single Factor input

Anova test appears in the new worksheet.

The ANOVA analysis will generate several results, including the F-value, the degrees of freedom, and the p-value. The F-value measures the ratio of the between-group variability to the within-group variability, and the p-value is the probability that the difference between the means is due to chance. If the p-value is less than the level of significance, you can conclude that there is a significant difference between the means of the groups.
