n South African Journal of Industrial Engineering - A non-zero sampling plan for the moderation of examination papers




The moderation of examination answer books is an area where quality assurance is essential, and should be employed to ensure that an examination paper's standard, content and span, marking, etc. are fair and reasonable. A scientific procedure is given for finding the minimum number of answer books to moderate (sample size) so that the statement - that no answer book in a set will contain more than a prespecified proportion of errors - can be made with a pre-specified confidence. The procedure is an extension and enhancement of previous research [7], and guarantees a statistical statement in all cases.

Gehalteversekering is belangrik by die moderering van eksamen antwoordstelle om te verseker dat die standaard, inhoud, omvang en akkuraatheid van eksaminering billik en volgens aanvaarbare norme verloop het. 'n Wetenskaplike prosedure word voorgestel waarvolgens die minimum getal antwoordstelle (steekproefgrootte) vir moderering bepaal kan word sodat die stelling dat geen antwoordstel in 'n groep meer as 'n vooraf-gespesifiseerde aantal foute sal bevat nie met 'n voorafgespesifiseerde vlak van vertroue gemaak kan word. Die prosedure is 'n uitbreiding en verfyning van vorige navorsing [7], en waarborg in alle gevalle 'n statistiese uitspraak.
