Webb12 sep. 2024 · How is Simpson’s reciprocal index calculated? Using the values we found earlier, Simpson’s Index can be calculated as: D = 2,668 / (105* (105-1)) = 0.244. We can also calculate Simpson’s Index of Diversity as 1 – D = 1 – 0.244 = 0.756. We can also calculate Simpson’s Reciprocal Index as 1 / D = 1 / .
