A simple technique for collecting, analyzing, and interpreting evaluative data

Best Liked/Least Liked (BL/LL) is a straightforward technique for collecting information used in evaluation. The technique is composed of stages (data collection, data analysis, and data interpretation) that are characterized by the ease with which they are accomplished. Further, the technique admits of flexibility in both range of applicability (some achievement testing and the measuring of effect) and scope of use (it can be narrowly focused or used to collect information on unintended outcomes). The technique is described here and examples are presented of its use both narrowly and broadly focused, and in service of both achievement testing and affective measurement.
