Our Take
JASP provides a point-and-click interface for common statistical analyses, including frequentist and Bayesian methods, with results presented in readable tables and plots. It can be a useful option for students and researchers who want to explore data and report analyses without writing code for every step.
An accessible interface does not make a statistical choice appropriate automatically. Results still depend on the study design, measurement quality, model assumptions, prior choices for Bayesian analyses, and how missing data are handled.
Choose analyses based on your research question and study plan, inspect assumptions and effect sizes, and report uncertainty rather than relying on significance alone. Save the analysis file and document relevant settings so another researcher can review or reproduce the work.
