I’m taking a statistics course on line through Coursera, and this is quite a challenge since my last high school math was in 1955, and although this class is not “math,” the instructor certainly uses words like fraction, percentage and square root. So I find myself often going to Google to find explanations. Today (week 5 of a 6 week class) the instructor (who is from Cape Town and has a bit of an accent in English) told us about Student’s t-test. The reason it’s called that is the man who came up with this test worked for a brewery, and had to publish anonymously. Since it is now known who he was, I don’t know why they don’t just call it the Gosset t-test. Maybe statisticians are a little OCD?
I’m using this video to flesh out what the instructor told us—I watched his video twice and still didn’t get it.
