Absolute Frequency Value

AKA: Event Frequency.
Context:
- It can be a member of a Frequency Table.
- It can range from being an Actual Frequency Value to being an Expected Frequency Value.
- It can range from being a High Frequency Value to being a Low Frequency Value.
- It can be an Experimental Frequency Value, if it is associated with a Random Experiment.
- …
Example(s):
- 5 is the Frequency Value for Frequency Function [math]\displaystyle{ f }[/math](a, {b, [math]\displaystyle{ c }[/math], a, [math]\displaystyle{ b }[/math], a}).
- …
Counter-Example(s):
- any Relative Frequency Value.
- any Percent Value.
- any Ratio Value.

- In statistics the 'frequency of an event [math]\displaystyle{ i }[/math] is the number n_i 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 n_i 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 f_i for all [math]\displaystyle{ i }[/math] and tabulating or plotting them leads to a frequency distribution.

- The frequency of a particular data value is the number of times the data value occurs. For example, if four students have a score of 80 in mathematics, and then the score of 80 is said to have a frequency of 4. The frequency of a data value is often represented by f.
- A frequency table is constructed by arranging collected data values in ascending order of magnitude with their corresponding frequencies.

- 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.
