Biased sampling: This activity requires a bag of 50 objects of two sizes, and a small scale. Assorted miniature candy bars can be used for the larger objects, while M&Ms or Skittles can be used for the smaller ones. The number of objects of each size is known; say there are 20 large ones and 30 small ones. Students are divided into groups. Some groups are instructed to attempt to draw a simple random sample of five items, while others draw a stratified sample containing two large items and three small ones. Each group weighs its sample and multiplies the result by 10 to estimate the total weight of the population of objects. Which sampling method is more accurate in this situation? Why?
