Question

The median of the data 10, 39, 71, 42, 39, 76, 38, 25 is

  1. 39
  2. 42
  3. 78
  4. 25

The correct answer is: 39


    Re-arranging the data we get
    10 , 25 , 38 , 39 , 39 , 42 , 71 , 76
    The no. of element = 8  , which is even number.
    Then the median of this data is
    space space space space fraction numerator left parenthesis 4 t h plus 5 t h right parenthesis e l e m e n t over denominator 2 end fraction
equals fraction numerator 39 plus 39 over denominator 2 end fraction
equals 39
    Where 4th and 5th both are 39.
