The most likely value of the median height in the distribution is 48 meters based on the choices in the options given.

The total number of observations in the distribution, n = 26

  • Class interval _ Frequency _ cumm/Frequency
  • 15- 30 _________ 2 _________ 2
  • 30 - 45 ________ 3 _________ 5
  • 45 - 60________ 12 _________17
  • 60 - 75 ________ 4 _________21
  • 75 - 90 ________ 1 _________22
  • 90 - 105 ________2 ________ 24
  • 105 - 120 _______ 0 ________ 24
  • 120 - 135 _______0 _________24
  • 135 - 150 _______2 _________26

The median value of the distribution can be calculated thus :

  • 1/2(n+1)th term

  • 0.5(27) = 13.5th term

  • This means the median will lie inbetween 13 and 14th terms in the distribution.

  • From the Cummulative frequency column, the 13th and 14th terms falls in the 45 - 60 class interval

  • Therefore, the median value should be within the Interval 45 - 60

Therefore, only 48 falls within that interval from the options given, hence, it is the most probable value of the median.
