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.
What is an example of variable interval schedule of partial reinforcement?
An example of a variable interval schedule of partial reinforcement is receiving a bonus at work on average every two weeks. The reinforcement (bonus) is given based on the passage of time (variable interval) and not every time the desired behavior occurs (partial reinforcement).
How do the four schedules of reinforcement work?
The four schedules of reinforcement are fixed ratio, variable ratio, fixed interval, and variable interval. Fixed ratio provides reinforcement after a set number of responses, variable ratio provides reinforcement after a variable number of responses, fixed interval provides reinforcement after a set amount of time has passed, and variable interval provides reinforcement after a variable amount of time has passed. These schedules can influence the frequency and consistency of behavior.
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

In math what is an interval?
a variable
What is partial reinforcement?
Partial reinforcement is a conditioning schedule where the desired behavior is not reinforced every time it occurs. This can lead to behaviors being more resistant to extinction compared to continuous reinforcement, where reinforcement is given each time the behavior occurs. Examples of partial reinforcement schedules include fixed ratio, variable ratio, fixed interval, and variable interval.
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 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 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,
What are four types of intermittent schedules of reinforcement?
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.
