Derive the mathematical relationship between correlation and Euclidean distance when each data point has been been standardized by subtract- ing its mean and dividing by its standard deviation.

Here, we further explore the cosine and correlation measures.


Let x and y be two vectors where each vector has an a mean of 0

and a standard deviation of 1. For such vectors, the variance (standard

deviation squared) is just n times the sum of its squared attribute values

and the correlation between the two vectors is their dot product divided

by n.
