The sample median is the middle value. (b) Since the median is the value dividing the ranked sample observations in half, it remains the same regardless of the size of the largest measurement. The number of bins can be changed by editing the. However, if 9 bins are specified, minitab generates an 8-bin histogram. Constructing a 9-bin histogram requires manual specification of the bin cut points. Recall that this formula is an approximation, and therefore either 8 or 10 bins should suffice for assessing the distribution of the data. 1 17 0 median observation rank is (0. 5)(80) + 0. 5 = 40. 5 x0. 50 = (14. 9 + 14. 9)/2 = 14. 9. Q1 observation rank is (0. 25)(80) + 0. 5 = 20. 5. Q3 observation rank is (0. 75)(80) + 0. 5 = 60. 5.
