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.

2 categorical independent variable and 1 interval dependent variable statistical test?
Two way ANOVA
Is year a categorical variable in statistics?
It can be though more often it is a variable on the interval scale (when looking for trends over time).
When do you use uniform distribution?
When, over a given range, the probability that a variable in question lies within a particulat interval is equal to the size of that interval as a proportion of the range.
What does justify your selection mean?
This statement means that you need to justify the choice of your selection. For example, if you choose a specific type of variable i.e., nominal, interval, etc. You need to show proof as to how you can statistically justify why you choose this particular variable. How can you justify the outcome of this type of variable chosen.
What is a continuous random variable?
In the simplest setting, a continuous random variable is one that can assume any value on some interval of the real numbers. For example, a uniform random variable is often defined on the unit interval [0,1], which means that this random variable could assume any value between 0 and 1, including 0 and 1. Some possibilities would be 1/3, 0.3214, pi/4, e/5, and so on ... in other words, any of the numbers in that interval. As another example, a normal random variable can assume any value between -infinity and +infinity (another interval). Most of these values would be extremely unlikely to occur but they would be possible. The random variable could assume values of 3, -10000, pi, 1000*pi, e*e, ... any possible value in the real numbers. It is also possible to define continue random variables that assume values on the entire (x,y) plane, or just on the circumference of a circle, or anywhere that you can imagine that is essentially equivalent (in some sense) to pieces of a real line.
Which reinforcement schedule produces the fastest extinction rate?
continuous reinforcement - giving a reward every time a desired action is presented
Mr. Smith teaches first grade. At different times during each hour he makes it a point to notice a child who is on task and to give that child praise. What schedule of reinforcement is he using?
variable interval schedule

What is variable ratio and variable interval?
different between variable intervals and fixed ratio
What is lifetime variable?
Nothing, but you can speak about the lifetime of a variable: the time-interval in which the variable exists.
Is age an interval variable?
yes
What are the two schedules of reinforcement that produce the most effective rates of response?
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.
What are some schedules of reinforcement?
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.
What is a reinforcement schedule that results in consistently high productivity?
Fixed-Interval Schedule
What level of measurement is grade level?
· 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,
