Measurement Systems Analysis Quiz

What is a gage?

• A person who measures materials

• A device used to obtain measurements

• A system for calibrating machines

• A method of estimating measurements

What is a measurement system?

• A network of systems used to monitor production

• A system of rules for measuring employee performance

• A computer-based data collection system

• A collection of operations, procedures, environment, gages & personnel used to assign a number to the characteristic being measured

What is reference value?

• A value of an artifact or ensemble that serves as an agreed upon reference for comparison

• The average value obtained from multiple measurements

• A historical measurement used as a comparison

• The value provided by the operator

What is discrimination?

• The process of eliminating outliers in measurement

• The ability of an operator to distinguish between units of measure

• The difference between two measurement devices

• The capability of a measurement system to detect small changes of the measure characteristic

What is the purpose of a measurement system analysis (MSA) study?

• To ensure employees follow measurement protocols

• To improve product design

• To evaluate the accuracy and precision of a measurement system

• To collect statistical data on product tolerances

Who should be involved in the selection of suitable measurement systems?

• Only the quality control team

• Production operators

• External consultants

• Cross-functional team including quality, engineering, and operators

What should instrument discrimination be in relation to the product tolerance?

• Equal to product tolerance

• Twice the product tolerance

• At least one-tenth of the product tolerance

• Half of the product tolerance

What is bias?

• The tendency of measurements to be higher than the actual value

• The inconsistency of repeated measurements

• The difference between the observed average measurement and the reference value

• A type of error due to faulty equipment

What is linearity?

• The ability of an instrument to measure in a straight line

• The difference in the bias values through the expected operating range of the gage

• The repeated accuracy of measurements

• The standard deviation of multiple measurements

What is stability?

• The total variation in the measurements obtained with a measurement system on the same master or part when measuring a single characteristic over an extended time period

• The consistency of measurements taken by different operators

• The variability of measurements over time

• The difference between minimum and maximum values
