Sigma Statistics: Level 3 (4e)

Completely updated to reflect recent changes in the New Zealand Curriculum, Sigma Statistics has been reorganised to provide full coverage of the NCEA Level 3 Statistics Achievement Standards. To reflect the intent of the new curriculum and the new Level 3 Achievement Standards that now allow students to take a "statistics only" course in Year 13, we have titled this new book Sigma Statistics rather than Sigma Mathematics, the predecessor title. New features: Bootstrapping - new statistical technique for developing informal confidence intervals for the median, and mean. Randomisation - new statistical technique for assessing the significance of experimental results. Seamlessly integrated with the new iNZight and Visual Inference Tools (VIT) software. Numerous new and updated datasets for time series, bivariate data analysis, statistical inference and experiments. Wide-ranging selection of statistically based reports - all in one place! Full coverage of experimental design - the types of blocking, controls, treatments, means effects and more! Specially commissioned new apps - a boxplot generator that superimposes the informal confidence interval, interactive apps for exploring the effect of parameter changes on the binomial, Poisson and normal distributions. Risk and relative risk. Inclusion of discussion about deterministic and probabilistic models. New simulations. New interactive spreadsheets
