The total area of a histogram used for probability density is always normalized to 1. If the length of the intervals on the x-axis are all 1, then a histogram is identical to a relative frequency plot. Histograms are sometimes confused with bar charts. In a histogram, each bin is for a different range of values, so altogether the histogram ...
Probability distribution fitting or simply distribution fitting is the fitting of a probability distribution to a series of data concerning the repeated measurement of a variable phenomenon.

In statistics, the Jonckheere trend test [1] (sometimes called the Jonckheere–Terpstra [2] test) is a test for an ordered alternative hypothesis within an independent samples (between-participants) design.

Histogram of 10,000 samples from a Gamma(2,2) distribution. Number of bins suggested by Scott's rule is 61, Doane's rule 21, and Sturges's rule 15. Sturges's rule is not based on any sort of optimisation procedure, like the Freedman–Diaconis rule or Scott's rule. It is simply posited based on the approximation of a normal curve by a binomial ...
For a set of empirical measurements sampled from some probability distribution, the Freedman–Diaconis rule is designed approximately minimize the integral of the squared difference between the histogram (i.e., relative frequency density) and the density of the theoretical probability distribution.
