In this tutorial, you have learnt how to perform a one-way ANOVA test in Microsoft Excel, and you also know how to interpret the results.Create Pareto chart in different versions of Excel including Excel 2016, Excel 2013, Excel 2010 and Excel 2007 in simple steps with examples. I’ll discuss these in more detail and show you how to perform these in Excel in future tutorials. There are many types of post-hoc tests available, such as Tukey, Bonferroni and Holms’. To investigate significant results further, you will need to perform post-hoc tests. So, you will not know which specific group is different from the rest. It’s very important to understand that the test will not tell you where these differences lie. Now, if your one-way ANOVA result was significant (P≤α), then the test can only tell you that there is a difference between the group means. In other words, each group on average performed more or less the same on the vertical jump test. Therefore, there is no difference between the means of my 3 groups. So, since my P value is greater than my alpha value of 0.05, we will fail to reject the null hypothesis. Or, when P >0.05, we will accept the null hypothesis and reject the null hypothesis. This means that when P ≤0.05, we will reject the null hypothesis and accept the alternative hypothesis. So, remember before when you specified your alpha value? There is a difference between the means of my 3 groups There is no difference between the means of my 3 groups F crit – The F critical value this is calculated based on the F and df valuesīefore I interpret the P value for the one-way ANOVA test, let me describe my null and alternative hypotheses.P-value – The P value for the one-way ANOVA test.F statistic (F) – The test statistic in the one-way ANOVA test.It is calculated by dividing the SS by the df Mean square (MS) – The average variation between or within the groups, depending on the row you are looking at.3-1) the df within the groups is calculated by subtracting the number of groups in the analysis from the total number of observations (e.g. Degrees of freedom (df) – The df between groups is calculated by subtracting 1 from the number of groups in the analysis (e.g.Sum of squares (SS) – Quantifies the variability either between the groups, or within the groups.Total – The sum for the SS and df for the first 2 rowsĮach column of the table represents a different output.Within Groups – The results when the source of variation is within groups.Between Groups – The results when the between groups is classed as the source of variation.The results here are split into three rows. New Workbook – Place the results in a completely separate Excel fileįor my example, I’ll select the second option and call the sheet Results.New Worksheet By – Have the results placed on a new worksheet, and you can give that sheet a name.Output Range – Lets you highlight a region within the sheet where you want the results to be entered.I will keep this set at 0.05 for this exampleįinally, you need to select the Output options. Usually this is set at 0.05, meaning that if the P value is ≤0.05, you would reject the null hypothesis and accept the alternative hypothesis. This is essentially your significance threshold. The next option is to specify your alpha level. If you highlighted the labels in your first row when selecting the input range, then tick that option. If your data was entered in rows instead of columns, you could select the Rows option. In my example, I will select the by columns option because each group’s data is in a separate column. Next, you need to select how the data are grouped (in columns or rows). You can highlight the labels in the first row if you want (more on this shortly). The first thing you need to do is to select the Input Range this is essentially the data we want to run in the analysis. Then select ANOVA: Single Factor and click OK.
To perform a one-way ANOVA in Excel, Go to Home>Data Analysis. Now we are ready to perform the one-way ANOVA. Now, when you click on the Data ribbon, you should see a Data Analysis button in a sub-section called Analyze. Then ensure you tick the Analysis ToolPak add-in, and click OK.

To install the toolpak, go to File>Options.Īt the bottom, you want to manage the Excel add-ins and click the Go button. This is an add on created by Microsoft to provide data analysis tools for statistical analysis. To be able to perform the one-way ANOVA test easily in Excel, it’s best to install or activate the Analysis ToolPak. What I want to do now is to perform a one-way ANOVA to determine if there is a significant difference between the average height measures of my 3 groups. So, that’s an overview of my example data.
And as you can see, I have 15 participants in each group.
