Complete paired comparisons data was obtained by use of multiple rank order (MRO) in the context of gathering rank order preferences of grade six students, their parents, and teachers for instructional objectives. Partially balanced incomplete block designs with two associate classes were used in the MRO instruments instead of the usual balanced…

This study investigates four widely used methods of collecting direct similarity judgments for nonmetric multidimensional scaling: rating scale, triads, rank order of pairs, and conditional rank order. (Author/PN)

The superiority of multiwave designs over two-wave designs in the measurement of individual growth and change is explored by examining the increase in reliability afforded by collecting additional waves of data. Results are discussed in terms of the impact on longitudinal studies of individual change. (SLD)

Data from 2-, 3-, 6-, and 7-point rating scales were analyzed to determine whether scale length affected response patterns. Results indicate that data configurations are relatively invariant with changes in number of scale points. (Author)
