Which of the following is NOT a measure of precision 8 O A s
     Which of the following is NOT a measure of precision? 8 O (A) standard deviation O (B) median O (C) variance ·(D) range  
  
  Solution
The range is not a measure of precision.
The range of values often considers an aunt of confidence probability which depends on the distribution of the error around the mean value. the other parameter such as median, standard deviation, and variance all are measures of precision around a central value.
