Experimental probability
Record, describe, and analyse the frequency of outcomes from probability experiments to develop an understanding of relative frequency as an estimate of probability
Suggested ages 11–13
Evidence of understanding
- Conduct a coin-toss experiment, record results in a frequency table, and calculate relative frequencies
- Compare experimental results with theoretical probability and explain discrepancies
- Predict that relative frequency approaches theoretical probability as the number of trials increases
Assessment prompt
If Experimental probability rolls a die 60 times and records the results, can they compare how often each number came up with what they'd expect in theory — and explain why they might not match perfectly?
