Relative Frequency Flashcards

The proportion of times an event occurs, calculated as the frequency of the event divided by the total number of trials.

Relative Frequency = Frequency of Event ÷ Total Number of Trials.

Relative frequency is used to estimate probabilities based on experimental data.

Relative frequency is based on experimental results, while theoretical probability is based on expected outcomes.

The running total of relative frequencies as trials are conducted.

A graph showing how relative frequency changes as more trials are conducted, often stabilising around the theoretical probability.

The accuracy of relative frequency improves as the number of trials increases.

If a coin is flipped 50 times and lands on heads 30 times, the relative frequency of heads is 30 ÷ 50 = 0.6.

Relative frequency can be used to predict future outcomes if the conditions remain the same.

Relative frequency is calculated after conducting an experiment to analyse the likelihood of an event.
