Applied Science: Ecology and Simpsons Diversity Index

Applied Science: Ecology and Simpsons Diversity Index

Rating
0.0 stars

Students practice calculating Simpson's Index of Diversity using playing cards as "species." Then they will use the equation and a sample set of data to calculate Simpson's Index of Diversity for a representative sample. Students can also conduct their own studies to obtain data.
