To find the midpoint of each layer can be obtained two ways:Method 1: limit the floor.1st floor, from the average of the sum between the limits of class 1 is on the ground floor and upper floor of the 24-floor 1 is 38.The middle tier 1 = (25 + 38)/2 = 62/2 31.2 find out from the average of the sum of the lower limit, the second floor is the upper limit of 39 and the second floor is 53.The middle tier 2 = (39 + 10)/2 = 2, 92/46.3rd floor, from the average of the sum between the limits of the third floor is the ground floor and the upper limit of 54 class III is 63.The Middle floor, 3 = (54 + 68)/2 = 122/2 61.4th floor, from the average of the total ground floor, between the limits of 4 is 69 and the upper floors of the 4th floor is 83.The middle tier 4 = (69 + 83)/2 = 152/2 76.5th floor, from the average of the sum between the limits of a 5-floor is on the ground floor and upper limit of 84 grade 5 is 98.The middle tier 5 = (84 + 98)/2 = 182/2 91.
