a method of sampling data in which information from past outcomes is used to reduce the chances of collecting future data that correspond to poor outcomes. A group of individuals randomly chosen from the population of interest is evaluated, and the information gathered is used to concentrate additional selection efforts where they are most likely to be successful.
