Simulating Sampling Communities and Calculating Diversity Indices with Scrabble Game Tiles

    Using tiles from a Scrabble game, we present methods to create simulations of sampling exercises and to develop diversity indices. The tiles represent species, and so a known sampling universe (100 tiles) allows comparing a sample with the known distribution of species. We then offer several variations to simulate different kinds of sampling (larger sample size, more samples), alter the rarity of species, and simulate the effect on diversity of an invasive species and the subsequent eradication of the invasive. Interactive data sheets are presented to make the calculations, and to allow the exercises to be completed in a 50-minute time period.
