Qualitative Vs Quantitative

When you calculate risk by using the SLE and ALE values, is this qualitative or quantitative? According to Shon Harris it is qualitative but I am not 100% sure if I understand correctly. Qualitative is based on opinions and with using the formula's to calculate looks more like quantitative? Please give me your thoughts on this. Well Sir..u right ..Going purely by definition.. **Quantitative** are..AV..EF..SLE..ARO..ALE..Perform Countermeasures ..means..it results in concrete probability percentages **Qualitative** are..Scenario based than calculator based.. ..means..u rank threats on a non numeric scale..to evaluate them ..offcourse ur judgement ..intuition..experience are keys here.. **Hybrid**..This is best
