· Dependent variable ( student's academic achievement ) : It depend on the way that we use it to write the score (if we write it as a letter it will be an ordinal ,but if we write it as number it will be an interval). · Independent variable ( intelligent ) : Interval, · Independent variable ( attention ) : Interval,
different between variable intervals and fixed ratio
A variable measured at the interval or ratio level can have more than one arithmetic mean.
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.
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.

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.
