The largest value minus the smallest value. In statistics, a distribution is the set of all possible values for terms that represent defined events.
There are two major types of statistical distributions. The first type has a discrete random variable. This means that every term has a precise, isolated numerical value. An example of a distribution with a discrete random variable is the set of results for a test taken by a class in school. The second major type of distribution has a continuous random variable. In this situation, a term can acquire any value within an unbroken interval or span. Such a distribution is called a probability density function. This is the sort of function that might, for example, be used by a computer in an attempt to forecast the path of a weather system.

Is the uniform probability distribution's standard deviation proportional to the distribution's range?
no
How do you find the semi-interquartile range with only the mean and standard deviation?
In general, you cannot. If the distribution can be assumed to be Gaussian [Normal] then you could use z-scores.
Can the inter quartile range be zero?
Yes, if you have a distribution with very little spread.
Which distribution is used to find probabilities about the number of independent events occurring in a fixed time period with a known average rate?
The Poisson distribution. The Poisson distribution. The Poisson distribution. The Poisson distribution.
How do find the midrange of a set of numbers?
find the mean in a set of frequency distribution
