# Absolute Experimental Frequency

(Redirected from Experimental Frequency)

An Absolute Experimental Frequency is an empirical frequency for Random Experiment Outcomes that occur within some given Random Experiment Event.

**AKA:**Random Experiment Trial Frequency.**Counter-Example(s)****See:**Expected Frequency, Theoretical Frequency, Experimental Probability.
