Result
Shannon Index Calculate the Shannon Diversity Index (H'). — free online calculator.
Formula
- Shannon Index Calculate the Shannon Diversity Index (H'). calculates its result from Sum, P I. It uses the formula H' = −Σ(p_i × ln(p_i)); J' = H'/H_max. Change any input to recalculate the result instantly.
- The main inputs are Species 1 Count, Species 2 Count, Species 3 Count, Species 4 Count. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Shannon Index Calculate the Shannon Diversity Index (H').
- Species 1 Count: 50
- Species 2 Count: 30
- Species 3 Count: 15
- Species 4 Count: 5
Using Sum = 2, P I = 3, the calculated result is -6.591673732.
