A Classroom Exercise in Sampling Technique
Teaching about sampling problems leads to a very theoretical understanding of the difficulties encountered when selecting a representative sample. A classroom hands-on demonstration has been developed that looks at the two important sampling considerations, sample size and non-homogeneous sample materials. This classroom activity makes use of readily available M&M candies for the sample size and Nerds for the non-homogeneous sample exercises. Results from the past four years are given.
