1. The following attributes are measured for members of a herd of Asian elephants: weight, height, tusk length, trunk length, and ear area. Based on these measurements, what sort of similarity measure from Section 2.4 would you use to compare or group these elephants? Justify your answer and ex- plain any special circumstances. The possible similarity measures can be narrowed down to these: Euclidean distance, Hamming distance, simple matching coefficient, Jaccard coefficient, cosine similarity, and correlation.
