Guttman Scale Analysis by Means of IBM Equipment

Scalogram analysis.

“…If the statements are to be considered a Guttman scale, then certain conditions must be met with respect to the pattern of check marks recorded in the table, the most important of which is that "from a person's rank ^ Suchman (1950) provides a good description of the scalogram board, a device used by members ofthe Research Branch, Information and Education Division, Army Service Forces, in doing scalogram analyses. Kahn andBodine (1951), andFord (1950) describe procedures involving IBM equipment.…”

Attitude modification and anxiety reduction.

“…The scalogram technique was thus used as a method of item selection, and items were discarded if the individual item reproducibilities proved to be low. An IBM adaptation of Guttman's scalogram technique, similar to that described by Kahn and Bodine (7), was used in the analyses. The results indicated extremely low levels of reproducibility when all 14 of the original items were considered.…”
