A quantitative risk estimate is always exact because it uses numbers.

### Why this is right Quantitative methods use numbers, but their results depend on data, assumptions, and cost estimates. The lesson warns that numerical calculations can create a false sense of precision. ### The concept A quantitative assessment can support comparisons and return-on-investment decisions, but it is not automatically reliable just because it is expressed numerically. Historical information may be incomplete, and estimates of frequency or impact may be uncertain. The result should be interpreted in light of its evidence. ### The other options - **The claim that numerical estimates are always exact**: numbers can be estimates rather than direct measurements, so the result can be uncertain even when the arithmetic is correct. ### Terms - **Quantitative assessment**: risk analysis using numerical values, probabilities, or financial estimates. - **False precision**: a result that appears more exact than the supporting information justifies. ### Remember Correct arithmetic does not make uncertain inputs certain.
