The following attributes are measured for members of a herd of Asian ele- phants: 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.
What will be an ideal response?
These attributes are all numerical, but can have widely varying ranges of
values, depending on the scale used to measure them. Furthermore, the
attributes are not asymmetric and the magnitude of an attribute matters.
These latter two facts eliminate the cosine and correlation measure. Eu-
clidean distance, applied after standardizing the attributes to have a mean
of 0 and a standard deviation of 1, would be appropriate.
