In the context of ergonomics QA, inter-rater reliability refers to:
Answer: The degree of agreement between two or more assessors evaluating the same task
Inter-rater reliability measures how consistently different evaluators apply an ergonomic assessment tool to the same situation.
Which type of error in ergonomic measurement occurs when a tool consistently underestimates or overestimates the true value?
Answer: Systematic (bias) error
Systematic error (bias) causes measurements to be consistently off in one direction, unlike random error which varies unpredictably.
A continuous improvement philosophy that focuses on eliminating waste and maximizing value from the worker's perspective is known as:
Answer: Lean thinking
Lean thinking targets the elimination of non-value-added activities (waste) while preserving and enhancing value for the end user.
When evaluating whether an ergonomic intervention had a statistically significant effect on injury rates, an ergonomist should use:
Answer: Hypothesis testing with an appropriate statistical test
Hypothesis testing (e.g., chi-square, t-test) determines whether observed differences are likely due to the intervention rather than random chance.
Which element is MOST critical for ensuring the sustainability of ergonomic improvements over time?
Answer: Embedding ergonomics into standard work procedures and management systems
Sustainability requires that ergonomic principles be integrated into normal operational processes rather than treated as a separate initiative.
A company's ergonomics program uses a balanced scorecard approach. Which perspective would include the metric 'percentage of ergonomic hazards corrected within 30 days'?
Answer: Internal process perspective
Corrective action completion rates measure internal operational efficiency, which falls under the internal process perspective of the balanced scorecard.
In an ergonomics QA context, a 'false negative' result from an ergonomic screening tool means:
Answer: A high-risk job was incorrectly classified as low risk
A false negative occurs when a tool fails to detect an actual hazard, potentially leaving workers exposed to unaddressed ergonomic risk.
