Non-parametric methods in statistics include methods which do not rely on an assumption that the data are observations from a particular probability distribution. In this video, we’ll see one of those methods, the sign test for matched pairs.

Notes on the video: The Sign Test
Calculating Binomial Probabilities
The sign test uses the binomial probability distribution. To calculate binomial probabilities, you can use the binomial distribution probability table or the probability distribution calculator. Both the table and the app are available on the menu under Probability Distribution Calculator.
