Abstract
It is suggested that nonparametric techniques deserve greater recognition and use in psychology. The appropriateness and benefits of these procedures are discussed and limitations acknowledged. Traditionally, nonparametric procedures seem portrayed as inferior to more popular parametric tests in both teaching and practice although much psychological data reflects less than interval measurement. Respecting the importance of precision and the need to develop questions allowing quantitative assessment, deterrents to greater interest in and use of nonparametrics are explored. The operational appropriateness, flexibility, computational simplicity, freedom from often untenable assumptions, and expanding interpretative possibilities of nonparametric procedures encourage greater consideration and use.
