Arrange the following steps in a k-nearest neighbors analysis of a classification problem in the most appropriate order (assume k is fixed):
a) For each point to be classified, find the k closest training observations and classify using the most common class.
b) For each point to be classified, calculate the distance from each training observation using an appropriate distance metric.
c) Standardize the predictor/feature variables if appropriate to do so.
