MQM 227 – Operations Management | 100 Statistical Quality Control & Sampling Questions on SPC, Control Charts, Cpk | Illinois State University

This document includes 100 fully answered multiple-choice questions from Chapter 13 of MQM 227 – Operations Management at Illinois State University. It covers core topics in Statistical Quality Control (SQC), including the use of control charts (p-chart, c-chart, mean chart, range chart), process variation (common vs. assignable), process capability (Cp, Cpk), and acceptance sampling strategies. Also included are sampling methods for attributes and variables, design and specification limits, and defect analysis using statistical tools. The questions explore advanced applications such as calculating lower and upper control limits, interpreting control chart signals, understanding probability distributions like normal and Poisson, and analyzing producer’s and consumer’s risk via OC curves. Key figures such as Genichi Taguchi are referenced in relation to variability reduction and customer-focused quality design. This resource is highly suitable for students in operations management, quality control, industrial engineering, and supply chain programs. It supports exam readiness, statistical application exercises, and quality system planning across service and manufacturing sectors.
