Temperature in Fahrenheit or celcius. In order to be interval, there must be equal distances between equal increments... That is one degree difference must always mean the same thing but zero cannot mean absence. Temperature in Kelvin is ratio because zero means the absence of heat... But not so in other temperature metrics. This is important because 80 is not twice as hot as 40 in most metrics but in Kelvin it is.

What is a variable interval schedule?
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
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.
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 Jersey numbers of soccer players is an example of a variable?
nominal
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).
What is a variable interval schedule?
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.
In math what is an interval?
a variable
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
How do you find interval estimate?
There are different types of interval estimates. Given a rounded value for some measure, the interval estimate, based on rounding, is the interval from the minimum value that would be rounded up to the given value to the maximum value that would be rounded down to the given value. For example, given 4.5 with rounding to the tenths, the minimum of the interval is 4.45 and the maximum is 4.55 so that the interval estimate is (4.45, 4.55). Statistical interval estimates for a random variable (RV) are probabilistic. For example, given some probability measure (for example 95% or 5% significance level), the interval estimate for a random variable is any interval such that the probability of the true value being inside that interval is 95%. Often the interval is symmetrical about the mean value of the RV that is being estimated, but this need not be the case - particularly if the RV is near an extreme of the distribution.
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.
What level of measurement is school 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,
Is land area interval variable?
Yes, land area is considered an interval variable because it can be measured on a continuous scale with equal units between values.
