Statistical quality control at statistics canada

Abstract

Over the past several years statistical quality control methodologies at Statistics Canada have evolved frotn forrnal Product Control (k Acceptance Sampling By Attributes) to a more complete use of all quality control information obtained to achieve what is now called Acceptance Control. The use of this additional information allows us to continually adapt our quality control methods to the existing conditions of survey operations. In this context this paper reviews the general approach to statistical quality control and its relation to survey processing operations in Statistics Canada.
