This article illustrates how to make an **ANOVA** Table in Excel. An **ANOVA** table is helpful in deciding whether you can accept or reject the Null Hypothesis for a dataset. You can use the Data Analysis tool in Excel to easily create an Anova table. Follow the article to use the analysis tool with your datasets.

## Introduction to ANOVA in Excel

ANOVA is the abbreviation of Analysis of Variance. In Excel, it is a method to obtain the values required to test the **Null Hypothesis**. Excel allows us to apply this method for the following three different cases.

**ANOVA: Single Factor****ANOVA: Two-Factor With Replication****ANOVA: Two-Factor Without Replication**

The single factor is applicable when there are multiple data samples and you need to perform the hypothesis test for differences in those samples only.

The two-factor with replication applies when each sample data is divided into similar groups, and you need to perform the hypothesis test for differences within those groups and within different samples.

The two-factor without replication applies when you need to perform the hypothesis test difference within each sample and within different samples.

You can make an Anova table using the **Data Analysis** tool in Excel. However, you may need to activate the tool to be able to access it. The following steps will be sufficient for that.

- Go to
**File>>Options**or press**ALT+F+T**. - Select the
**Add-ins**tab>>Manage**Excel Add-ins**>>**Go**. - Check the
**Analysis ToolPak**checkbox>>Click**OK**.

After that, you can access the Data Analysis tool from the Data tab as shown below.

## 1. Using the ‘ANOVA: Single Factor’ Option to Make an ANOVA Table in Excel

Assume you have a dataset containing the marks obtained by a group of students on two different tests as follows. Now you want to analyze the dataset to find out if there are any significant differences between the test results.

Follow the steps below to perform a one-way or single-factor ANOVAÂ on the dataset in Excel for that.

📌**Steps:**

- First, select
**Data>>Data Analysis**. Then choose**Anova: Single Factor**from the analysis toolbox and click**OK**.

- Next, you will see the
**Anova: Single Factor**dialog box. Now select the entire dataset including the labels (**B4:C12**) for**Input Range**. Then mark the radio button for**Columns**beside the**Grouped By**option as the data in this dataset are grouped by columns. Next, check the**Labels in first row**Keep the**Alpha**value to**0.05**. After that, mark the radio button for**Output Range**, enter the cell reference where you want to make the Anova table, and click**OK**.

- Finally, you will see the following table in the specified output location.

## 2. Utilizing ‘Anova: Two-Factor With Replication’ Option

Assume you have a similar dataset where the students are divided into two different groups. Now you want to see if there is any significant difference in performance between the two groups.

Follow the steps below to perform a two-way or two-factor ANOVA with replication on the dataset in Excel for that.

📌**Steps:**

- First, select
**Data>>Data Analysis**. Then choose**Anova: Two-Factor With Replication**from the analysis toolbox and click OK.

- Next, you will see the
**Anova: Two-Factor With Replication**dialog box. Now select the entire dataset including the labels (**B4:D12**) for**Input Range**. Then enter 4 in the**Rows per sample**field as each group has 4 students. Keep the**Alpha**value to**05**. After that, mark the radio button for**Output Range**, enter the cell reference where you want to make the Anova table, and click OK.

- Finally, you will see the following table in the specified output location.

## 3. Using the ‘Anova: Two-Factor Without Replication’ Option to Make an ANOVA Table

Assume you have a similar dataset as follows and you want to find out if there are significant differences among individual performances along with the test-wise performances.

Follow the steps below to perform a two-way or two-factor Anova without replication on the dataset in Excel for that.

📌**Steps:**

- First, select
**Data>>Data Analysis**. Then choose**Anova: Two-Factor Without Replication**from the analysis toolbox and click OK.

- Next, you will see the
**Anova: Two-Factor Without Replication**dialog box. Now select the entire dataset including the labels (**B4:D12**) for**Input Range**. Then check the**Labels**Keep the**Alpha**value to**0.05**. After that, mark the radio button for**Output Range**, enter the cell reference where you want to make the Anova table, and click**OK**.

- Finally, you will see the following table in the specified output location.

## How to Interpret an ANOVA Table in Excel

We perform variance analysis to test if the **Null Hypothesis** is true for a dataset or not. The Null Hypothesis suggests that two sets of data are the same and the difference between them is insignificant or purely by chance. We can decide whether this hypothesis is true or not for a dataset using the Anova table obtained by performing Anova on that dataset.

The following three properties in the Anova table will help us to do that.

**F-value****F crit-value****P-value**

First, we need to check if the **F-value** is higher or lower than the **F critical value**. **F > F crit **rejects the Null Hypothesis and indicates that the two possibilities are not the same. Therefore there is a difference between the two sets of data. **P-value<Alpha **(**0.05**) also rejects the Null Hypothesis indicating that the difference between the two sets of data is statistically significant.
