CISM study material · question 211 of 1000

Which comparison does a semi-quantitative scale allow that a purely qualitative one cannot express?

  1. That a risk is unacceptable rather than acceptable
  2. That scores of 70 and 71 differ insignificantly while 36 and 70 differ meaningfully
  3. That a risk has been assessed more recently than another
  4. That one risk affects more assets than another
Show the answer

Answer: B. That scores of 70 and 71 differ insignificantly while 36 and 70 differ meaningfully

SP 800-30 gives exactly this illustration: bins or scales allow relative comparison between values in different bins or within the same bin, so the difference between 70 and 71 is insignificant while 36 and 70 is significant.
