It involves the examination across cases of a single variable, focusing on three characteristics: the distribution; the central tendency; and the dispersion Example: a frequency distribution chart 2. Exploratory analysis is an approach to analyzing data for the purpose of formulating hypotheses. “Multivariate or Factor analysis” are used to uncover the latent structure (dimensions) of a set of variables. It reduces attribute space from a larger number of variables to a smaller number of factors and allows the definition of statistically consistent cluster. Example: Multivariate cluster analysis from three measurements of femur properties source From Wikipedia Possibility to define the characteristics of statistically homogenous groups.
