listwise deletion

a strategy for dealing with the problem of missing data in which an entire case record is excluded from statistical analysis if values are found to be missing for any variable of interest. For example, consider a researcher examining the relationships among grade point averages in high school, scores on college admissions tests, and grade point averages in college. If, for whatever reason, a value has not been recorded for one of those variables for certain participants, all of the information for those individuals is removed from the data set and analyses are performed only on the remaining (complete) records. Also called casewise deletion; complete-case analysis. Compare pairwise deletion.

social relations model

a general framework used in studies of interpersonal perception in which a person’s behavior with a particular partner is considered to reflect aspects of the larger group to which the two individuals belong, as well as aspects of the individual emitting the behavior, aspects of the partner, and qualities unique to the two individuals’ relationship with one another. The model makes use of a round-robin rating design in which participants rate one another and their degree of perceptual accuracy in different areas is evaluated. Of particular interest are individual accuracy, or how well a person’s judgments of an individual correspond to how that individual tends to behave across interaction partners; and dyadic accuracy, or how well someone can uniquely judge how a specific individual will behave with him or her. [developed in 1981 by U.S. social psychologist David A. Kenny]
