Marine biologists investigated the species diversity of zooplankton communities across 8 different sampling stations in a deep-water fjord following an environmental remediation scheme. The index of diversity (ddd) for each station was calculated and recorded in the table below.
| Sampling Station | Index of diversity (ddd) |
|---|---|
| Station A | 3.2 |
| Station B | 4.8 |
| Station C | 5.1 |
| Station D | 4.8 |
| Station E | 2.7 |
| Station F | 6.3 |
| Station G | 4.8 |
| Station H | 1.9 |
The team used the following formula to calculate the index of diversity (ddd):
d=N(N−1)∑n(n−1) d = \frac{N(N-1)}{\sum n(n-1)} d=∑n(n−1)N(N−1)where:
At some of these sampling stations, the recorded values were N=160N = 160N=160 and ∑n(n−1)=5300\sum n(n-1) = 5300∑n(n−1)=5300.
Determine which stations had these values. Use the formula and the table provided to show your working.
