\end{figure} Fig. 1 and Fig. 2 both show strong correlation, but of two different kinds.
  1. For each diagram, use a single word to describe the kind of correlation shown.
  2. For each diagram, suggest a reason, in context, why the correlation is of the particular kind described in part (a). Fig. 3 is the same as Fig. 2 but with the point \(A\) marked.
    Fig. 4 shows information about the same LAs as Fig. 2 and Fig. 3. \begin{figure}[h]

  3. Point \(A\) in Fig. 3 and point \(B\) in Fig. 4 represent the same LA. Explain how you can tell that this LA has a large population. \section*{END OF QUESTION PAPER}
