A variable ratio schedule is applied to operant learning. It is the rate in which a reinforcement (reward) for a particular behavior is obtained. A variable ratio schedule is when the reinforcement is sometimes won, sometimes not won.
Example:
1. Casinos. The reinforcement would be the money won. Sometimes the money is won, but sometimes it isn't.
2. Abusive relationships. Sometimes the partner that is doing the abuse is nice, sometimes he/she isn't nice. The "kindness" is the reinforcement.
The behavior is the same, but the rate in which the reinforcement is obtained varies.
Fixed-ratio schedule - reinforcement depends on a specific number of correct responses before reinforcement can be obtained. Like rewarding every fourth response. Variable-ratio schedule - reinforcement does not required a fixed or set number of responses before reinforcement can be obtained. Like slot machines in the casinos. Fixed-interval schedule - reinforcement in which a specific amount of time must elapse before a response will elicit reinforcement. Like studying feverishly the day before the test. Variable-interval schedule - reinforcement in which changing amounts of time must elapse before a response will abtain reinforcement.
A variable ratio schedule of reinforcement is best for building persistence. This schedule provides reinforcement after a varying number of desired behaviors, which helps to maintain consistent motivation and effort over time. The unpredictability of reinforcement keeps individuals engaged and persevering in their actions.
Individuals are least likely to satiate on variable ratio schedules of reinforcement. This is because reinforcement is given after a variable number of responses, leading to a consistent level of motivation and engagement in the behavior.
Answer:Continuous and partial. Partial reinforcement schedule can be: fixed-interval, fixed-ratio, variable-interval, or variable-ratio. See the related link below for more details. Answer:Continuous reinforcement is most effective at the start so the subject learns to associate the behavior with the reward. Afterword this is learned a switch to partial reinforcement can be done - more specifically, a variable-ratio schedule produces the strongest response and slowest extinction.
A schedule of reinforcement that is based on the number of responses is called a ratio schedule. In ratio schedules, reinforcement is given after a specific number of responses. This type of schedule often leads to high rates of responding by the individual compared to other schedules.

different between variable intervals and fixed ratio
A slot machine exemplifies a variable ratio reinforcement schedule because players receive rewards (winnings) after an unpredictable number of plays. This means the reinforcement is not given after a fixed number of attempts, making it difficult for players to predict when they will win. The uncertainty and variability of the payouts encourage continued play, as players are motivated by the possibility of a reward at any time. This unpredictability is a key characteristic of variable ratio schedules, fostering a high rate of response.
The four schedules of partial reinforcement—fixed ratio, variable ratio, fixed interval, and variable interval—determine how often a behavior is reinforced. In a fixed ratio schedule, reinforcement occurs after a set number of responses, while in a variable ratio schedule, reinforcement is provided after a random number of responses, leading to high and steady rates of behavior. Fixed interval schedules reinforce behavior after a fixed amount of time has passed, resulting in a pause after reinforcement. In contrast, variable interval schedules reinforce behavior after varying time intervals, promoting consistent behavior over time due to unpredictability.
Variable-interval schedule (VI) is a reinforcement schedule in which reinforcement is provided for the first response that occurs after a variable amount of time from the last reinforcer or the start of the trial interval.

It is the ratio generated by dividing the Variable cost over total Sales/Revenue
Partial reinforcement is when an individual is rewarded on some, but not all, trials. There are multiple variants of partial reinforcement (fixed interval, variable interval, fixed ratio) but the schedule that is most likely to have the slowest extinction rate is variable ratio, meaning that after a certain number of trials between two values, a reward will be given. A real life example of this is gambling.
