A fisheries biologist who had to estimate the number of prawns in two aquaculture ponds chose three locations at random within each pond and deployed four traps at each, using a total of 24 traps. This design is summarised below.
The biologist said ‘I have a two-factor design, where the ponds are one factor and the trap location is the second, so I will use a two-factor ANOVA with replication.' (a) Is this appropriate? What analysis would you use for this design?
