REST helps researchers, graduate students, and academics choose the correct statistical test for their study — without needing advanced statistics knowledge. Instead of searching through textbooks or guessing which test to use, REST conducts a smart, adaptive interview about your research design. It asks only the questions relevant to your specific study, then recommends the right statistical test with a clear scientific explanation.
