A marine biologist is designing an experiment to model the swimming speed, v m s−1v\text{ m s}^{-1}v m s−1, of a rare species of deep-sea amphipod at various water temperatures, T ∘CT\text{ }^\circ\text{C}T ∘C. The planned main study involves measuring the speed of 150 amphipods individually across five different temperature zones.
Before starting the main investigation, the biologist conducts a pilot study using 8 amphipods.
Briefly explain one reason why conducting this pilot study is important before carrying out the main investigation.
