Welcome to the Reseach Randomizer Quick Tutorial.
This brief tutorial describes five examples of how Research Randomizer can be used to solve common research tasks such as randomly selecting numbers from a phone directory, randomly assigning subjects to experimental conditions, or drawing a random sample of individuals from a population. The examples are intended to be illustrative, not exhaustive.
[Note to Instructors: You are also welcome to use or adapt the Random Assignment Assignment from Social Psychology Network to teach about random sampling and assignment.]
