Which statement best describes the purpose of quantitative evaluation in safety training?

• A. To rely on personal opinions.
• B. To judge based on impression.
• C. To prioritize narrative feedback.
• D. To prove assertions with data.

Answer: (D)

Quantitative evaluation uses numbers and metrics to show the impact of safety training. It provides objective evidence that training changed knowledge, skills, or behavior by measuring things like test scores, completion or retention rates, observed safe practices, or incident and near-miss rates before and after training. This approach lets you prove assertions with data rather than relying on opinions or impressions, and it supports trend analysis, benchmarking, and informed decisions about program improvements. The other options describe subjective inputs—personal opinions, impressions, or narrative feedback—which don’t provide the numeric proof of effectiveness that quantitative evaluation aims to deliver.
