Microsoft Excel was no doubt one of the most used tools by companies and commercial companies both national and international, becoming a fundamental ally when making sums and spreadsheets within the accounts of these companies.
Allowing us to perform various functions such as data tables, even graphs and we can even create a web page with excel, using this tool we would save time and even money in managing specific accounts and 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 get returns high and efficient within their activities, being able to use formulas, since its launch it has achieved great uses by more people, and until now it has not declined its rank.
That's why we have to know each of its functions and features in so that when we use them, the process is much more immediate and we would already have a basic knowledge of the use of the tool which for some people is complicated to use, but for others it is simple.
That is why, in this article, we will explain the steps for create and run an Anova table in an Excel spreadsheet so easy and fast.

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

Of course, when we get into Excel, we have the worksheet, which is the one that contains the complete grids that the cells are in, the best thing is that the worksheets they can be personalized with a signature or a name, bottom left.
It also contains the 'option 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 cell borders, being a visual and permanent menu that we can use it any way we want.
If we want to create structural data tables, Excel is the best option, allowing us to access rows and columns for better management of the tool, facilitating our work to be done at some point in various ways.
How to calculate an ANOVA table in Excel
This Anova option in Excel it is used a lot by users, obtaining excellent results, the first thing we need to do is enter Excel and go to the visual menu located at the top of our document.
So, we look for the option that indicates "tools" and press there, then other options will be split and we click on "data analysis", then we click on "Anova" and we select and if it is "two factors" with reply "or" two factors without answer "and we pressed" accept ".
The next step is to write the range of cells we want to use and obviously 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 have to add where we want that 'Anova' data is included.
And ready, we click "accept" and Excel will provide automatically the results you do find where we entered them earlier.
Data to perform a one-way ANOVA in Excel
The data allows us to analyze specific cases that we want to investigate on a given situation. In the following example we can observe the dynamics of data collection to be able to measure the variables within a hypothesis.Read How to create and add a Paypal payment button on my website - Step by step
Next, we will present the grades 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 to determine with which teacher grades are lowered.
|Group 1||Group 2||Group 3||Group 4||Team 5|
After drawing our table with the data in EXCEL let's go to the 'DATA' tab and we choose the 'Data analysis' tool, then in the pop-up tab we select 'Analysis of the variance of a factor' in the next window we specify the data range we want to do (Input range) for this step we select the entire table with the data, without forgetting to select the 'Labels in the first row'. Then in a separate cell we select the output range. Finish by clicking on 'Accept' and showing our analysis.
Formulas for making an ANOVA table
|Origin of the variations||Sum of squares||Degrees of freedom||Mean of squares||F||Probability||Critical value for F.|
Interpretation of the results of an ANOVA
By following the previous steps correctly we will be able to have a satisfactory result in the cases we want to analyze. This interpretation is the variance of several hypotheses that can be presented within a given situation.
If we look at the probability, it gave 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 it can be realized 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 be understood very well .
Value of F in my ANOVA table
This value indicates the statistics of two variances that can have values greater or less than depending on the data with respect to the measurement carried out . We observe that the value of F is 1,15 rounding, which makes us understand that the variation is minimal.
Advantages of using Excel for an ANOVA table
One of the biggest advantages is that it is a completely versatile and well-functioning tool, which allows us to select ranges of cells, to be able to create data forms, becoming an indispensable platform within the workplace at the macro level.
Another good thing about Excel is that it allows us to add or insert various graphs , such as bars, pie charts, we can even place images and organization charts within the sheet we are using right now.
What used to cost us hours before will be much easier with Excel, since it has an interface extremely efficient to work in different areas and perform different functions.
