The North Island has the bigger population, but does the South Island have the bigger motor vehicle engines? An introduction to bootstrapping

confidence intervals ages 15 - 18 years

The lessons introduce the concept of resampling through bootstrapping, leading to the formation of a confidence interval of the difference between two means or two medians. The students experience sampling variation and bootstrapping visually through the aid of technology and manually through a physical exercise involving data cards of a sample from a very large population. A confidence interval of the difference between two population parameters is formed and interpreted. Lastly the experience using technology is formalised.
