(As a quick reminder, the variance is the average squared distance of your sample points from the mean. The Means and Variances should be self-explanatory. Now letР Р†Р вЂљРІвЂћСћs take a look at what this all means: To Р Р†Р вЂљРЎС™prettifyР Р†Р вЂљРЎСљ this, click the HomeР вЂ™Р’В tab, head over to the CellsР вЂ™Р’В section, click Format,Р вЂ™Р’В and hit AutoFit Column Width: Now just hit OK.Р вЂ™Р’В LetР Р†Р вЂљРІвЂћСћs take a look at the results: IР Р†Р вЂљРІвЂћСћll just leave it on New Worksheet Ply.Р вЂ™Р’В The results will be posted in a new worksheet on the same project. You can also choose to set up a New WorkbookР вЂ™Р’В and save the results to a new file. Under Output options,Р вЂ™Р’В you can choose Output RangeР вЂ™Р’В and select where to paste your data. (To be more precise, it means that if there is no true difference between the variances, 5 percent of the time we will falsely conclude that there isР вЂ™Р’В a difference.) An alpha of 0.05 means that we can be 95 percent confident in our solution. Your AlphaР вЂ™Р’В is your level of statistical significance. Click the Labels boxР вЂ™Р’В so that Excel can use these headers properly. Notice that IР Р†Р вЂљРІвЂћСћm selecting the headers as well as the data. Now click in the Variable 1 RangeР вЂ™Р’В box and select your first treatment data:Р вЂќР вЂћnd do the same for the second treatment. Start off by clicking the DataР вЂ™Р’В tab, then head over to the AnalysisР вЂ™Р’В section, and hit Data Analysis.Р вЂ™Р’В Now select F-Test Two-Sample for VariancesР вЂ™Р’В and hit OK. With that caveat out of the way, letР Р†Р вЂљРІвЂћСћs say you wanted to compare two samples, each of them made up of units that you randomly assigned to one of two treatments, like this:

(Or, you could download this normality test excel spreadsheetР вЂ™Р’В I put together for you.) To be genuinely rigorous, you would need to build your own normality test. WARNING: F-tests assume that your sample data comes from a normal distribution.Р вЂ™Р’В Worse, Excel offers zeroР вЂ™Р’В normality testing capabilities. This can also be a good way to compare 2 treatments in order to see if one of them produces more consistentР вЂ™Р’В results. Compare Variances With an F-TestР вЂќР’В«efore you compare two sample averages, itР Р†Р вЂљРІвЂћСћs usually a good idea to to compare their variances first. This post should take between 22 and 44 minutes to read and toy with.

Today, weР Р†Р вЂљРІвЂћСћre going to learn how to run statistical tests in Excel.Р вЂ™Р’В WeР Р†Р вЂљРІвЂћСћll cover F-tests to compare variances, t-tests to compare 2 averages, and ANOVAs to compare multiple averages. If youР Р†Р вЂљРІвЂћСћve ever tried to set up a legitimate statistical test in Excel, you already know itР Р†Р вЂљРІвЂћСћs painful, but if you have the Analysis ToolPak enabled, things get a bit easier.
