elementary statistics
My name is Stephanie and I worked as an adjunct professor of mathematics for Jacksonville University and Florida State College at Jacksonville before starting this site. This website was originally set up to help my students in STA2023 to understand elementary statistics. It’s since grown to cover AP Stats and calculus-based statistics. You’ll find help for SPSS, Minitab, Excel and other popular technology for stats. There are (as of January 2014) over 700 articles, videos, calculators and tables. and it’s still growing!

I earned both an MAT (Mathematics Education) and an MFA in Creative Writing. I’ve been teaching mathematics and statistics since 2006. I’m a member of both Pi Mu Epsilon (the mathematics honors society) and Kappa Delta Pi (education honors society). I attended the University of Florida and FSU where I took two additional years of coursework in education and mathematics education. My publishing credits include the Sirius Elementary Statistics textbook published by Houghton Mifflin, for which I was co-author.

    Thanks so much for reporting this. It was a connectivity issue which is now fixed.
    Please try your transaction again, and I hope you find the book helpful.

    I can’t post a question on a relevant page due to an error when I try, describing permissions.

    The question I was trying to post is:

    “Find the Sum of Sq. for the following numbers: 3,5,8.
    Step 1: Find the mean by adding the numbers together and dividing by the number of items in the set:
    3 + 5 + 7 / 3 = 15 / 3 = 5”

    I could be mistaken, but isn’t the mean of 3, 5, 8 = 16/3 = 5+(1/3) ?
    From the first part of the equation “3 + 5 + 7 / 3 = 15” I believe there may be some sort of mistake? I think 3+5+(7/3) = 10+(1/3), not 15

    Thanks for your correction, Andrew. It was missing parentheses. I added these to clarify the mean (and changed 8 to 7).

    Hi Stephanie,

    I like your tag line of “Statistics for the rest of us” and I’m interested in your thoughts on this application that is a more learner-centered tool for conducting and understanding statistics.

    I look forward to your feedback.
