A member оf yоur dаtа science teаm was tasked tо cluster customers along many dimensions with k-means. She mentions that she tried clustering with and without normalizing (standardizing) the data, and decided to report her unnormalized solution. She further explains, that her plot of “k vs sum of square error” for normalized data is fairly linear, without any clear and distinct drops, unlike with the unnormalized data. Do you trust her results? Why or why not? Be sure to include in your answer a clear explanation of the goal of normalization.
