    • In statistics the 'frequency of an event [math]\displaystyle{ i }[/math] is the number ni of times the event occurred in the experiment or the study. These frequencies are often graphically represented in histograms.
    • We speak of absolute frequencies, when the counts ni themselves are given and of (relative) frequencies, when those are normalized by the total number of events:
      • [math]\displaystyle{ f_i = \frac{n_i}{N} = \frac{n_i}{\sum_i n_i}. }[/math]
    • Taking the fi for all [math]\displaystyle{ i }[/math] and tabulating or plotting them leads to a frequency distribution.

    • Empirical Frequency: The number of times an outcome has been observed to occur during repeated trials of an experiment; also called Experimental Frequency.
    • Frequency: Measures how often something occurs within some given distance or time period.
    • Theoretical Frequency: The number of times an outcome is expected to occur during repeated trials of an experiment based on probability principles.
