Exam tips
- Convert mixed units before substituting (e.g. km → m, hours → minutes).
- For reverse percentage problems, identify whether the ‘new’ value is after an increase or decrease.
- Show working: method marks often depend on a correct ratio or percentage set-up.

Statistics & probability
Summaries of data, probability rules, and expectation.
Mean
Arithmetic average.
mean = (sum of values) / (number of values) Estimated mean (grouped data)
Midpoints mᵢ, frequencies fᵢ.
≈ Σ(mᵢ × fᵢ) / Σfᵢ Range
Spread of data.
range = largest value − smallest value Median & mode
Median: middle value when ordered; mode: most frequent.
If there is an even count of values, median is the mean of the two middle values.
Probability of an event
Equally likely outcomes.
P(A) = (number of outcomes for A) / (total possible outcomes) Complement
Probability of not A.
P(not A) = 1 − P(A) Independent events
A and B independent.
P(A and B) = P(A) × P(B) Expected frequency
Trials n, probability p of success.
expected frequency ≈ n × p Topic Focus
Data & chance
- Mean uses all values and is pulled by outliers; median is often better for skewed data.
- Probabilities lie between 0 and 1; the sum of probabilities of all mutually exclusive outcomes is 1.
