The Student's T-Test

A single grape is not enough data. You need a population of data points. So if you tested 20 grapes on vine A and 20 vine B, you would have 40 data points in two populations. Then you enter all of it into Excel and then Excel automatically finds the mean, then does the t-test, then creates the p-value. Alright, quick fun thing to wrap this up. I've actually been shortening things when he call it the t- test. It's technically the students t-test because it's drawn from the students t distribution.
