Semi-quantitative Risk Assessment Methodology

Set of methods, principles, or rules to assess risk that uses bins, scales, or representative numbers whose values and meanings are not maintained in other contexts

Sample Usage: By giving the “low risk, “medium risk,” and “high risk” categories corresponding numerical values, the assessor used a semi-quantitative risk assessment methodology.

Annotation: While numbers may be used in a semi-quantitative methodology, the values are not applicable outside of the methodology, and numerical results from one methodology cannot be compared with those from other methodologies.
