Decomposing three dimensional contingency tables

A simple box-like diagram makes the task of teaching or analyzing three dimensional contingency tables much easier.

The Impact of Criminal Conviction Disclosure on the Self-reported Offending Profile of Social Work Students

Correspondence to University of Edinburgh, School of Social and Political Studies, 31 Buccleuch Place, Edinburgh, EH8 9JT, UK. E-mail: richard.perry{at}ed.ac.uk. Summary Data gathered at a Scottish institute of higher education between1986 and 2000 indicate a significant reduction in the scaleof self-reported offending behaviour by social work students.The change coincided with the introduction by the Central Councilfor Education and Training in Social Work (CCETSW) in 1989 ofa requirement that applicants for training disclose prior toadmission any criminal convictions recorded against them. Thearticle suggests that more prolific offenders have been deterredfrom applying to DipSW programmes and the social work professionneeds to take steps to create a more positive climate for therecruitment of those offenders who represent no more of a threatto users than non-offenders.
