Let , the no.of observations = n
given,
 no  of observations(n) = 12 which is even
           mid values                   =  n/2 , n/2 +1
                                               =12/2 12/2 +1
                                               = 6 , 7 observations
    given 6th and 7th observations are 14 and 15 respectively
   median of all 12 observations = (14 + 15) / 2
                                                   = 29/2
                                                   = 14.5
