Psychology and Statistics Collection
Tags | |
Hi everyone!
This collection is every equation, calculator, and dataset I created while working on the vCalc Project for St. Mary's College of Maryland. I worked primarily on the psychology and statistics aspect, which will be helpful for researchers and students alike to better understand inferential statistics and use the correct tests. Almost every inferential and descriptive statistic test you could possibly want is included in this collection, from correlations to parametric and non-parametric tests. It also includes a calculator that combines all of those statistics tests into one comprehensive, easy-to-use tool. The collection additionally holds several non-statistics-related psychology equations, including Weber's Fraction, Ricco's Law, and Bayes' Theorem, the latter of which I have applied in a couple of contexts. Bayes' Theorem for Disease Testing describes the risk to one person of having a rare disease, given that the test for it returned positive. Some equations in this collection may not be completely finished, so feel free to duplicate anything and try your hand at computer programming. Happy calculating!
Cheers,
Caroline Robertson
