n = 7 which is odd so median is the middle value of te data after arranging in ascending order. 1,1,2,4,5,6,7 median = (7+1)/2 th observation = 4th observation = 4 So median of the data is 4. Solution n = 7 which is odd so median is the middle value of te data after arranging in ascending order. 1,1,2,4,5,6,7 median = (7+1)/2 th observation = 4th observation = 4 So median of the data is 4..
