What Is the Advantage of the Standard Deviation Over the Average

question 43

Multiple Choice

What is the advantage of the standard deviation over the average deviation?

• A) Because the standard deviation requires squaring of deviations before further computation, positive and negative deviations do not cancel out.
• B) Because the standard deviation does not require squaring of deviations, it is easy to tell whether deviations are positive or negative.
• C) The standard deviation removes the units from the calculation, and delivers a pure number.
• D) The standard deviation expresses the average deviation in percentage terms, so that different choices can be more easily compared.
• E) The standard deviation transforms subjective probabilities into objective ones so that calculations can be performed.
