It differs from other types of statistical analysis in that, rather than testing a previously established hypothesis, data mining slices and dices data in many different ways in an effort to reveal something useful. For example, association rules can be used to analyze data in a database for frequent if/then patterns. Support and confidence criteria can then be used to rank the most important relationships within the data.
