• S2 Option - Sampling & Estimation

  This session introduces and explains the chapter Sampling & Estimation in Statistics 2.

   

  The following concepts are explained in video lessons:

  Part 1 - Sampling Theory explained; reasons for using samples to study a population discussed

  Part 2 - the Distribution of Sample Means, X-bar, explained

  Part 3 - concept of Unbiased Estimates explained; Methods of Random Sampling discussed

  Part 4 - Unbiased Estimates for population mean (μ), population variance (σ²) and population proportion (p) explained

  Part 5 - Example 1 discussed: calculating sample mean and sample variance for a given sample of data

   

  The exercise file section contains notes to the above video lessons on Sampling & Estimation
