Abstract
RAN: A computer program to estimate random response patterns in objective tests Computar program for random response. In the psychological measurement, especially in personality, the paper-pencil method is the usual device between the psychologist and allied professions. The score obtained by a person examined can have questionable validity if the responses were random. To identify this problem, different methods have been used. The random response is a challenging situation for the measurement research and diagnosis in cognitive performance and personality, when they have been measured by test of dichotomous type. In this study a computer program that implements the Charter's method of point estimate and confidence intervals is presented in order to identify if the score obtained can be considered random. We analyze and discuss this program uses in the research and professional practice.
