Several colleges and universities like Purdue are mining data they have about students to try to improve retention. The institutions analyze years' worth of data on which students did well and which did poorly, and what variables — whether they be SAT scores, financial-aid status, or attendance at the dining halls — correlate with those successes or failures. Using those data, colleges try to predict which students are likely to drop out — and intervene before the students themselves even know they're in trouble.
