This is the first post on Hypothesis Testing. Click here to see the full list of statistics posts.
Hypothesis testing is one of the fundamental tools of experimentation. It is also sometimes called difference testing, because the question underlying most experiments is whether (or not) there is a difference between the behavior of two groups.

Am I Really Better Than Quan In Long Jumping?
Wrapping Up
Contemplating Quan
So I was thinking about challenging Quan to another contest, but this time in the standing long jump. I’ve heard he is good, but I’m much better at long jumping than holding my breath . I have some inside information from Dan that Quan averages 180cm per jump and that his jumps...
