A variable-ratio schedule reinforces a behavior after an unpredictable number of responses. Slot machines are a classic example of a variable-ratio schedule, as a gambler never knows exactly how many times they will have to pull the lever to hit the jackpot. Studying for unexpected quizzes would be better reinforced by a variable-interval schedule, where reinforcement is given after a variable amount of time has passed. Paying for a candy bar and checking the mailbox are not examples of behavior being reinforced on a schedule.
