Risk presented as a single numeric value (as in a quantitative analysis) does not guarantee greater accuracy compared to a risk matrix (as in a qualitative analysis), because of uncertainty that is inherent with probabilities and consequences.
Risk presented as a precise numeric value (as in a quantitative analysis) implies a greater level of accuracy when compared to a risk matrix (as in a qualitative analysis). However, the implied linkage of precision and accuracy may not exist because of the element of uncertainty that is inherent with probabilities and consequences.
