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.

In math what is an interval?
a variable
Is age an interval variable?
yes
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.
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 is variable speed?
A Body has variable speed if it covers unequal distance in equal interval of time is known as Variable Speed
Can a variable measured at the interval or ratio level can have more than one arithmetic mean?
A variable measured at the interval or ratio level can have more than one arithmetic mean.
Is the set of all possible outcomes always finite?
No. If the variable is continuous, for example, height or mass of something, or time interval, then the set of possible outcomes is infinite.
