NZ Scholarship Statistics study guide
NZ Scholarship Statistics · Work through your exam, one topic at a time.
New Zealand Scholarship is an award that recognises top secondary school students, and Statistics is one of the Scholarship subjects students can attempt. It is aimed at the most able candidates: NZQA describes Scholarship assessments as designed to be challenging for the most able students in each subject, and to earn the award you are expected to show deep understanding of the subject, demonstrate high-level critical thinking, and apply your understanding to complex situations. Assessment is by written or spoken examination, or by a portfolio or report of work produced through the year, depending on the subject. Entry happens through your school, so speak to your statistics teacher early, because not all schools enter students and some enter only a small number of subjects. You do not have to be working towards NCEA to enter. Each assessment has between 3 and 5 parts, marked 0 to 8 per part and added to give your final result; candidates reaching the cut score receive Scholarship, and the very top students receive Outstanding Scholarship.

01Statistics (NZ Scholarship Statistics)
The NZ Scholarship Statistics exam rewards statistical judgement, not recipe-following. You are expected to critique study designs and reports, select and justify methods, interpret output in context, and communicate uncertainty. The single domain draws on study design, exploratory and multivariate data, probability, inference, and regression. Random sampling supports generalisation to a defined population; random allocation supports causal claims.

- Practice questionsA random variable X has E(X) = 12 and Var(X) = 9.
- FlashcardsStandard error of a mean. The standard deviation of the sampling distribution of the sample mean, equal to the population standard deviation divided by the square root of the sample size.
- Cheat sheetExperimental design: random allocation balances unmeasured confounders in expectation; blocking reduces variance by grouping similar units; pairing is blocking with block size two.
- Key termsRandom variable. A numerical quantity whose value depends on the outcome of a random process, so it takes values with associated probabilities.
- Study planMap the full Statistics domain into a personal topic checklist, marking each subtopic as confident, shaky, or unknown.
- Common mistakesCandidates treat the task as two separate 'describe the distribution' questions, a habit reinforced by earlier years where description alone earned credit.
