Statistics Calculators

  • Wide variety of calculators, simple interface
  • No background information about the various calculators

So, you finally obtain data. Now it’s time for statistical analysis—but wait! You can’t remember what a t-test is, or how to perform hierarchical multiple regression analyses. Well never fear. Thanks to the generosity of Daniel Soper, Ph.D., an assistant professor at California State University, Fullerton, all you need to remember is how to click over to Dr. Soper’s statistics calculators page. Organized into 21 categories, there are over 50 statistics calculators on the site (and all are offered free of charge). From analysis of variance, to chi square distribution, to probability, one simply needs to enter the relevant information when prompted and click “calculate” for results. True, this site does encourage calculator dependence (you know, like those people who need a calculator to compute 3 x 4), and it would be nice if Dr. Soper actually included a description of the unseen calculations so that users might actually learn to perform the analyses themselves. However, as a quick reference, this site is a very useful resource to the statistically befuddled researcher.
