Stats Cheat Sheet

Statistics: who would guess

Oh my god! I don't want to study statistics!
So, you have to take statistics, but you don't want to. Here are three reasons why you need to UNDERSTAND statistics and not just pass a stats class.

  • See the Twain quote below: Lies, damned lies, and statistics." If you don't understand how statistics work, how will you know whether the statistics have been manipulated to present a skewed result.
  • If you are in a doctoral program, you have to do research and that research needs to show at least some level of statistical understanding (whether you do qualitative or quantitative research).
  • Politics: politicians and their flunkies lie and you need to understand how they manage to do that and stay in office.
This wiki has been created as part of a final exam for EP 577, Educational Statistics, at the University of Tennessee, Knoxville. Our goal is to create a stats cheat sheet that will help us in an open book final without having to go through the book to find the appropriate information. This particular cheat sheet is totally legal and will be shared with other class members.

**NOTE: The definitions and formulas for the website have been taken from our course textbook Essentials of Statistics for the Behavioral Sciences, F. Gravetter & L.B. Wallnau and in-class discussions. This is our own cheat sheet and not an academic paper, so be aware of that if using the site. In the definition section, when we say The Book, we are quoting directly from the Gravetter & Wallnau text. We are not working on attributions and citations, but stats and how we can understand them.

A favorite Stats quote:

Figures often beguile me, particularly when I have the arranging of them myself; in which case the remark attributed to Disraeli would often apply with justice and force: "There are three kinds of lies: lies, damned lies and statistics."
- Autobiography of Mark Twain
