(a)[4]
Describe how random sampling could be carried out for plant species in the two fields.
(b)
Table 8.1 presents the outcomes of sampling in field A.
(c(i))[1]
Finish Table 8.2 for \textit{Primula veris}.
(c(ii))[2]
Using the data in Table 8.2, calculate Simpson’s Index of Diversity $(D)$ for field A. Show your working and give your answer to two decimal places. The formula is: $D = 1 - \sum \left( \frac{n}{N} \right)^2$
(c(iii))[1]
The $D$ value for field B was $0.45$. Compare the $D$ values for the two fields.
(i)[1]
Finish Table 8.2 for $Primula\ veris$.
(ii)[2]
Use the data in Table 8.2 to work out Simpson’s Index of Diversity ($D$) for field A. Show your working and give the answer to two decimal places.
(iii)[1]
For field B, $D$ equalled $0.45$. Comment on the $D$ values for both fields.
