, fori=1,...,n. Then sort the data ascending, the ordered data is denoted by/math-b0666fef7a24d86f4dc246703c85603d.png?v=0 "x_{(i)}\,\!")
, fori=1,...,n. The corresponding count of the value is denoted by/math-0ed19e8a34d384686bcbdb75b54cdf85.png?v=0 "c_i\,\!")
, , which is the frequency of the ith value. The relative frequency and cumulative frequency of are calculated as follows:

and /math-6c96448444a8c2a28079ff6a97fc268d.png?v=0 "CumulativeFrequency_k=\sum_{k=1}^N{c_i}/n\,\!")
, for k=1,...,n.
