What does relative frequency measure?

Relative frequency measures the frequency of an event occurring relative to the total number of trials or attempts. Specifically, it is calculated by taking the number of times a particular event occurs and dividing it by the total number of trials conducted. This gives a proportion that expresses how often the event happens in terms of the total outcomes, making it a practical way to estimate the probability of future occurrences based on experimental data.

In statistical contexts, relative frequency provides a valuable insight into the likelihood of events based on empirical observations rather than theoretical probability definitions alone. Hence, this concept helps in understanding and interpreting data from experiments or trials effectively.
