  1. Press Using randomisation on spreadsheets to enhance statistical understanding Neil Sheldon Manchester Grammar School Royal Statistical Society Centre for Statistical Education

  2. Press • Data in textbooks and examination papers are static • But data in the real world are dynamic • Every time you sample you get different data • And if the data are different the conclusions may be different too

  3. Press • Statistical concepts that everyone should understand • Probability is long-run relative frequency • All data should be understood against some sense of the background variation • Variation can be controlled by taking larger samples

  4. Press • Statistical concepts in MEI S1 • Data representation • Calculating summary data • especially the tricky issue of divisor n and n − 1 • The meaning of probability • The use of the binomial distribution • The concepts of hypothesis testing

  5. Press • Statistical concepts in MEI S2 • Correlation: PMCC and Spearman’s coefficient • Regression • The use of the Poisson distribution • including approximating the binomial • The use of the Normal distribution • including approximating the binomial and Poisson • Chi-squared tests on contingency tables

  6. Press • Statistical concepts in MEI S3 • Central limit theorem • The t distribution • Chi-squared goodness of fit
