Anova This example teaches you how to perform a single factor ANOVA (analysis of variance) in Excel. A single factor or one-way ANOVA is used to test the null hypothesis that the means of several populations are all equal. In Microsoft Excel, install the Analysis ToolPak add-in to gain access to a. The single factor ANOVA function takes several data columns as arguments.
In this Example, we will learn how to perform single factor ANOVA in Excel 2016.
A single factor ANOVA is used to test the null hypothesis. Which means the mean from all the population are all equal and alternate hypothesis is at least one among the mean is different.
All of the above might be confusing for some people, so let’s gear up & start learning ANOVA single factor in excel with the example.
Here we have marks of Three students in the table. Select the tab Data > Data Analysis as shown in below screenshot. Note: can’t find the Data Analysis button? Click here to load the Analysis ToolPak add-in.
Click on Data Analysis and its dialog box appears. Now select Anova: Single factor and click OK. Anova: Single factor dialog box appears. Fill the options as shown below. Click OK to get the stats for your data. Conclusion: if the value of F > F crit, we reject the null hypothesis. In this case, 16.59 > 3.40. Therefore, we reject the null hypothesis. The means of the three populations are not all equal. At least one of the means is different.

In this Example we will learn how to perform a single factor or One way ANOVA in Excel. A single factor or one way ANOVA is used to test the null hypothesis, i.e. the mean from all the population are all equal. And alternate hypothesis is at least one among the mean is different.
H0: μ1= μ2= μ3
H1: at least one mean is different.
Let’s take an example of marks scored in three subjects, to demonstrate One way ANOVA in Excel.
Step 1: On the top right corner of the data tab click data analysis.
Note: if you can’t able to find the Data Analysis button? Click here to load the Analysis ToolPak add-in.
Step 2: Select Anova: Single Factor and click OK.
Step 3: Click in the Input Range box and select the range A2:C10 and output range as shown below and click ok
The result will be
If F > F crit, we reject the null hypothesis. In this case F crit value is 3.402826 and F value is 0.071109. So we cannot reject null hypothesis. So mean of the all the three subjects are same.
If you want to test the mean of two subjects you can use T-Test.
