4. The scatterplot below shows measurements taken of 100 crabs of the Species Leptogra psus variegatus collected at Fremantle in Western Australia. Observations are plotted separately for males [circles] and females [triangles]. The correlation between the two variables, carapace width and rear width, is r = 0.99 for males and r = 0.98 for females. 12 14 16 18 20 Rear width (mm) 10 20 25 30 35 40 45 50 Carapace width (mm) (a) What type of variables are these two measurements?
