(of a particular outcome in a statistical experiment) the number of occurrences of a particular outcome divided by the number of trials.

the ratio of the number of observations in a statistical category to the total number of observations

A quantitative descriptor, expressed as a percent, of the relative distribution of individuals of a species in an area; it is calculated by Frequency of species A รท Total frequency of all species x 100.

A count of the number of occurrences of a data value in a sample, or the number of values falling within a fixed range, expressed as a proportion of the total number of observations. Data can be summarized in this manner by tabulating all the data values into distinct categories and then counting the number of times each category appears in the frequency distribution. This tabular summary is called a frequency table. A graphical representation would be a barchart or histogram. Relative frequencies are calculated in the Tabulation and Crosstabulation Statlets.
