I have a question about Question 3 b)ii from the 2018 paper
So the marking schedule says that the distribution of energy consumption in the North Island is roughly unimodal and symmetrical. However, in my answers, I said that North Island follows a bimodal distribution with two peaks at around 650 and 750.
I know that bimodal data has two peaks, but I often get confused when it is appropriate to label graphs as unimodal and when to label them as bimodal, especially when the data is clustered quite closely. Would I be incorrect in this case?
