Monte Carlo evaluation of implied orders as a basis for tailored testing
TAILOR, the computer program which implements
an approach to tailored testing outlined by
Cliff (1975), was examined with errorless data by
monte carlo methods. Three replications of each
cell of a 3 × 3 table with 10, 20, and 40 items and
persons were analyzed. Mean rank correlation coefficients
between the true person and item order,
specified by preassigned random numbers, and the
computed order produced by the program averaged
.96. The average proportion of items used was .48.
A marked tendency was observed for the program
to produce better results as the number of persons
and items increased
