different between variable intervals and fixed ratio
It is ratio.
The rise and the run.
The answer depends on whether the ratio is in the context of the starting value, or time (over which the change takes place), or some other variable.
If the first derivative of a function is greater than 0 on an interval, then the function is increasing on that interval. If the first derivative of a function is less than 0 on an interval, then the function is decreasing on that interval. If the second derivative of a function is greater than 0 on an interval, then the function is concave up on that interval. If the second derivative of a function is less than 0 on an interval, then the function is concave down on that interval.
it is either one number verses another like 10 cookies and Joe to took 4 and Judy took 6 the ratio between Joe and Judy would be 4:6 but if it's what Joe took verses to total it would be 4:10
Four types of intermittent schedules of reinforcement are fixed ratio, variable ratio, fixed interval, and variable interval. Fixed ratio schedules provide reinforcement after a set number of responses, while variable ratio schedules provide reinforcement after a varying number of responses. Fixed interval schedules provide reinforcement after a set time interval, while variable interval schedules provide reinforcement after a varying time interval.
A variable measured at the interval or ratio level can have more than one arithmetic mean.
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.
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.
Ratio: The ratio of the heights of two women is meaningful. For instance, one woman might be 4/5 the height of another woman.
There are two kinds of reinforcement schedules. The first is continuous reinforcement where desired behavior is reinforced every time. The second schedule is partial reinforcement where a response is reinforced part of the time. Within partial reinforcement, there are four schedules which include fixed-ratio, variable-ratio, and fixed-interval and variable- interval.
It is ratio.
interval
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.
