How to Do a T-Test for Beginners 

In this tutorial, I explain how to perform a t-test on Microsoft Excel 2013. If you are using the freeware Google Sheets, then most of this still applies. The test is really easy to calculate, but understanding the meaning and uses can be frustrating. In this tutorial, I try to explain this with different examples and trying to not get too technical for beginners. Remember, you want a minimum of 10 samples (n=10) for each group of data in order to develop a reasonable bell curve for the t-test to evaluate. Anything less than n=10 does not give us a reasonably accurate calculation. However, the more samples, the better!
