Question

Carlos is collecting data about the length of earthworms in his backyard. The shortest worm he found is 4 inches long; the longest worm is 8 inches long. If most of the worms are either short or long, which type of distribution is displayed in the population?

Answer 1

Continuous variation with disruptive selection

Answer 2

If Carlos finds that the majority of worms have small sizes of 4 cm and lengths of 8 cm, it can be said that the length has a distribution of two peaks. Drawing a histogram will result in a bimodal histogram, that is, with two peaks, where the valley corresponds to the lowest frequency. This data corresponds to a distribution of two normal distributions.
