Without a doubt, Microsoft Excel has been one of the most used tools by both national and international companies and commercial companies, becoming a fundamental ally when making summations and spreadsheets within the accounts of said companies.

Allowing us to carry out various functions such as data tables, also graphs and we can even create a web page with Excel, by using this tool we would be saving time and even money when managing accounts and specific data that we need at some point.

All those users who have to carry out projects related to the area of ​​numerical data, being able to obtain great and effective yields within their activities, being able to use formulas, since its launch it has been widely used by multiple people, and until now it has not declined. range.

That is why we must know each of its functions and characteristics so that when using them, the process is much more immediate and we would already have a basic knowledge of the use of the tool that for some people is complicated to use, but for others it is simple.

That is why, in this article, we will explain the steps to make and run an Anova table in an Excel spreadsheet easily and quickly.

Main features of Excel

Excel contains multiple features that help us carry out our activities with greater security and of course ease, among them we have the cells, which are part of the grid in our Excel document, the information that we want to analyze, add or subtract, we place them inside of the cells, which are identified by letters and numbers within the spreadsheet.

Of course, when we enter Excel, we have the worksheet, which is the one that contains the complete grid where the cells are present, the best thing about it is that the worksheets can be personalized with a signature or name, at the bottom left.

It also contains the ‘ribbons’, which are the icons that appear at the top of the Excel sheet, allowing us to place custom colors, we can also shade the borders of the cells, being a visual and permanent menu that we can use in any way. way we want.

If we want to make structural data tables, Excel is the best option, allowing us to access rows and columns for better handling of the tool, facilitating our work to be done at some point in various ways.

How to Calculate an ANOVA Table in Excel

This option of Anova in Excel is highly used by users, obtaining great results, the first thing we must do is enter Excel and locate ourselves in the visual menu that is located at the top of our document.

Then, we look for the option that indicates ‘tools’ and press there, then other options will be broken down and we click on ‘data analysis’, then we click on ‘Anova’ and select and if it is ‘two factors with replication’ or ‘two factors without replication’, and click on ‘accept’.

The next step is to write the range of cells that we want to use, and of course write in the dialog box the number of cases per condition in ‘rows per sample’, then we will get a text box, which indicates ‘output range ‘ where we must add where we want the ‘Anova’ data to be included.

And ready we click on ‘accept’ and automatically Excel will provide the results located where we placed them previously.

Data to run a one-way ANOVA in Excel

The data allows us to analyze specific cases that we want to study more deeply about a given situation. In the following example you can see the dynamic data collection to be able to measure the variables within a hypothesis.

Below we will present the notes of five groups of students, all students of the same subject, with the same material provided, same exams applied but with a different teacher. We will apply an analysis of variance in order to determine with which teacher the grades fall.

Group 1 Group 2 Group 3 Group 4 Team 5
10 fifteen twenty 10 12
fifteen 10 18 fifteen 13
fifteen 14 16 14 14
18 12 fifteen twenty twenty
13 18 14 14 18
twenty 16 16 fifteen 14
10 twenty 4 16 16
12 7 10 18 18
5 12 12 19 19
14 18 13 twenty 17
10 twenty 10 twenty eleven
10 twenty 16 fifteen 10
16 12 10 18 fifteen
19 5 10 17 14
fifteen 10 eleven 16 eleven
10 7 9 fifteen 16
10 9 8 eleven 14
17 10 10 10 18
7 16 10 5 twenty
16 fifteen fifteen 6 14
fifteen 12 17 8 fifteen
twenty eleven 19 14 12
8 eleven twenty 16 13
12 8 twenty 14 14
13 12 13 fifteen fifteen
10 twenty eleven 1 twenty
10 7 16 10 eleven

After capturing our table with data in EXCEL we go to the ‘DATA’ tab and we choose the ‘Data analysis’ tool then in the pop-up tab we select ‘Analysis of variance of one factor’ in the next window we specify the range of data that we want to perform (Input range) for this step we select the entire table with the data, not forgetting to select the ‘Labels in the first row’. Then in a separate cell we select the output range. Finishing by clicking ‘OK’ and displaying our analysis.

Interpretation of the results of an ANOVA

Following the previous steps correctly we can get a satisfactory result in the cases that we want to analyze. This interpretation is the variance of different hypotheses that may occur in a given situation.

If we look at the probability, it has given us a low range of 0.33 or we round to 0.40, which means that in at least one of the groups there is a minimal difference. Studying the average data we can realize that ‘Group 2’ has a lower grade than the rest, although not very different from ‘Group 1’ which means that the teachers assigned to these classrooms may not make themselves understood very well .

F value in my ANOVA table

This value indicates the statistics of two variances that can have higher or lower values according to the data with respect to the measurement that is carried out. F-value we observe that it is 1.15 rounding, which gives us to understand that the variation is minimal.

Advantages of using Excel for an ANOVA table

One of the greatest advantages is that it is a totally versatile and well-functioning tool, allowing us to select ranges of cells, to be able to create data forms, becoming an essential platform within the work environment at a macro level.

Another of the positive things about Excel is that it allows us to add or insert various graphics, such as bars, circular graphs, we can even place images and organization charts within the sheet that we are using at the moment.

What used to cost us to do for hours, with Excel will be much easier, since it has an extremely efficient interface to work in different areas and fulfill different functions.
