Relative frequency (AQA GCSE Maths): Flashcards

Probability calculated from experiments or surveys

$\frac{\text{frequency of outcome}}{\text{total frequency}}$

Shows frequency relative to all other outcomes

With larger samples or more trials

Find frequency, find total, divide

Probability estimated by carrying out experiments

Experimental probability approaches theoretical with more trials

Estimate becomes more reliable and accurate

$\frac{1}{4}$ or $0.25$
