KS4 – MYP 4–5 Mathematics | Statistics Core: So, what do you think?

Original 68-page MYP Mathematics booklet by Taylan Çeltik, supplied as a downloadable PDF. It covers sampling, statistical measures and spread, box-and-whisker plots, outliers, cumulative frequency, bivariate data, correlation and regression, with calculator work and contextual analysis. The command term analyse is developed through worked discussion and practice. The original question numbers, tables, diagrams, working spaces and selected answers are retained. The PDF includes three verified YouTube lesson links.

Statistical clarification: the 68–95–99.7 rule assumes an approximately normal distribution. A spread of one standard deviation is not a confidence interval for the mean.

Statistical clarification: similar mean and median do not by themselves show that data are normally distributed. Assess the distribution’s shape and other relevant evidence.
