Instances with values smaller than given value will be selected. Consistency of any subset can never be lower than that of the full set of attributes, hence the usual practice is to use this subset evaluator in conjunction with a Random or Exhaustive Key concepts when talking about datasets are instances, attributes, and the class (which is conventionally the last attribute).
