Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

A meadow has four kinds of butterflies, with $18$ , $12$ , $6$ and $4$ individuals. Find Simpson's diversity index, $D = 1 - \sum (n/N)^2$ .

Need a reminder? The key ideaShow

Simpson's diversity index: $D = 1 - \sum \left(\dfrac{n}{N}\right)^2$ , where $n$ is the number of one species and $N$ the total. Near 0: one species dominates. Larger: the numbers are even.

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
