Have you ever found yourself working with a spreadsheet full of data and wishing you could make more sense of the numbers? Have you reviewed sales or operations reports, wondering if there's a better way to anticipate your customers' needs? Perhaps you've even thought to yourself: there's got to be more to these figures than what I'm seeing! Data mining can help, and you don't need a Ph. D. in Computer Science to do it. You can forecast staffing levels, predict demand for inventory, even sift through millions of lines of customer emails looking for common themes--all using data mining. It's easier than you might think. In Data Mining for the Masses, professor Matt North--a former risk analyst and database developer for eBay.com--uses simple examples, clear explanations and free, powerful, easy-to-use software to teach you the basics of data mining; techniques that can help you answer some of your toughest business questions.
