Effect Size + Power Visualizer

Written By JC Pass

Power analysis is one of those things that sounds simple right up until you have to make an actual decision with it. The Original Matter Effect Size + Power Visualizer helps psychology and social science students explore how effect size, alpha, desired power, and sample size interact for common t-tests. It gives you a clearer visual sense of what your assumptions imply before you commit to a design.

JC Pass, MSc, is a social and political psychology specialist and self-described psychological smuggler; someone who slips complex theory into places textbooks never reach. His essays use games, media, politics, grief, and culture as gateways into deeper insight, exploring how power, identity, and narrative shape behaviour. JC’s work is cited internationally in universities and peer-reviewed research, and he creates clear, practical resources that make psychology not only understandable, but alive, applied, and impossible to forget.
