MONTE CARLO RESULTS FROM COMPUTER PROGRAM FOR TAILORED

INTERTAIL, the computer program which implements an approach to tailored testing outlined by Cliff (1975), was examined with errorless data in several Monte Carlo studies. Three replications of each cell of a 3 x 3 table with 10, 20 and 40 items and persons were analyzed.,Mean rank correlation coefficients between the true order, specified by pre-assigned random numbers, and the computed order produced by the program ranged from.93 to.99. Other efficiency measures are reported which also support the theory as a general measuring and ordering technique. Based on these results, program modifications are proposed as well as a data scheme which is to be used in further system testing.
