Illustrated Instructions
The opening screen of the sampling simulation displays all 100 animals in the population.
You can select between a random sample and a stratified sample directly below the population and then generate a sample of ten animals.
Below is an example of a random sample. Notice that animals selected are highlighted in the population and the total number of animals selected from each category is listed at the bottom of the simulation.
To start, select Random or Stratified sample. Each time you click the "Sample 10 animals" the number sampled from each category is displayed.
