Relative frequency (AQA GCSE Maths): Quizzes

Probability calculated from experiment data

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

Larger samples give more accurate estimates

$\frac{8}{30}$

Find frequency, find total, then divide

The estimate becomes more accurate

Experimental probability approaches theoretical

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

They may not reflect true probability well

The object might not be fair
