What is rank frequency?
Rank–size distribution is the distribution of size by rank, in decreasing order of size. This is also known as the rank–frequency distribution, when the source data are from a frequency distribution. These are particularly of interest when the data vary significantly in scale, such as city size or word frequency.

How to find the mean of a frequency distribution?
Add the values in the frequency column. The mean ( mu) is the sum of f ⋅M f ⋅ M divided by n n, which is the sum of frequencies. The mean is the sum of the product of the midpoints and frequencies divided by the total of frequencies. Simplify the right side of μ = 267 13 μ = 267 13.
How is the rank size distribution in Wikipedia?
Wikipedia word frequency plot, showing three segments with distinct behavior. A rank–size (or rank–frequency) distribution is often segmented into ranges. This is frequently done somewhat arbitrarily or due to external factors, particularly for market segmentation, but can also be due to distinct behavior as rank varies.
How are categories specified in a frequency distribution?
The categories are usually specified as consecutive, non-overlapping intervals of a variable. The categories (intervals) must be adjacent, and often are chosen to be of the same size.
