Study Design and Statistical Test Planner

This tool is designed to plan and evaluate your study for your HCI research. Enter your independent and dependent variables, estimated difference between extreme (minimum and maximal measures), and their pooled standard deviation. The tool use the statistical power estimate with R and the Superpower package. This tool only offers tips and help for beginners for quick start and is not a substitute for extensive research or input of your supervisor.
