Answer to Question 1

Data mining is analogous to physically sifting through great quantities of ore in the quest for gold. It utilizes information and techniques such as descriptive statistics, cross-tabulations, regression, and correlation, but also includes many advanced methods such as factor analysis, cluster analysis, discriminant analysis, and multidimensional scaling, for the purpose of uncovering patterns and discovering interrelationships within the data.
