Q: When an analyst attempts to find out if the variables themselves group in any
meaningful way,
Answer:
it is a data reduction method used to reduce the dimensionality of large data sets, by
transforming a large set of variables into a smaller one that still contains most of the
information in the large set Principal Component Analysis (PCA)
