# The Deciles for Ungrouped Data Example. Find the 7th decile or D7 of the following test scores of random sample of 10 students taking online learning: 25, 36, 22, 34, 42, 39, 28, 30, 43, and 37 Solution: Arrange the scores in ascending order 22 25 28 30 34 36 37 39 42 43 To find its D7 position, use the formula 7/10 N+1 and round off to the nearest integer Position of D_7= 7/10 N+1 = 7/10 10+1 = 77/10 =7.7 = 8 D is the 8tth element. Therefore D_7=39
