Statistics A Level *Fees Payable* at Rochester Independent College
Exam board: AQA
S1: Topics include numerical measures (averages, variances, range, quartiles etc.), probability (independence, mutual exclusivity, conditional etc.), the binomial distribution, the normal distribution (including the central limit theorem, confidence intervals for the mean sampling distributions etc.), correlation and regression.
S2: Topics include time series analysis (data that has a certain seasonal pattern), sampling methods, discrete probability distributions, interpretation of data and hypothesis tests.
S3: Topics include tests for independence using contingency tables and the χ2 distribution, distribution-free tests (the sign test, Wilcoxon sign-rank test, Mann-Whitney U test and Kruskal-Wallis test) and tests for correlation for both the product moment and Spearman’s rank correlation coefficients.
S4: Topics include combinations of normal random variables, approximations of the Poisson and binomial distributions by the normal distribution, Poisson approximation to the binomial, the t-distribution (including confidence intervals for a normal means and hypothesis tests for the same), approximate confidence intervals and hypothesis tests for proportions and the mean of a Poisson distribution using the t-distribution.
S5: Topics include the rectangular and exponential distributions, confidence intervals and hypothesis tests for the variance of a normal distribution using the χ2 distribution, χ2 goodness to fit tests for various distributions, twosample comparison tests for variance and mean of normal distributions using the F, t and normal distributions.
S6: Topics include experimental design (experimental error, randomisation, replication, control and experimental groups, blind and double blind trials etc.), analysis of paired comparisons using the paired t-test, analysis of variance (one-way, two-way and Latin squares), statistical process control (control charts for the mean, range, standard deviation and proportions, estimation of short-term standard deviation, tolerances) and acceptance sampling including operating characteristics.
Assessment method: 100% examination (three papers at AS level and three papers at A2 level), we do not offer the coursework option.
AS: S1, S2 and S3
A2: S4, S5 and S6
Overlap with other subjects: Any subject which has anything to do with the real world will find themselves using some or other aspect of statistics: Geography, Biology, Sociology, Psychology, Economics etc. Needless to say at A-level any overlap will be superficial but at degree level statistics can be an invaluable tool.
