Given :- Calculate 3rd decile and 70th percentile for the following data: 841, 289, 325, 225,784,729, 625,400,324,169 . Solution :- arranging data in ascending order we get, → 169, 225, 289, 324, 325, 400, 625, 729, 784, 841 . N = 10 terms now, → Di = {(N + 1) * i} / 10 → D3 = {(10 + 1) * 3} / 10 → D3 = 11 * 3/10 → D3 = 3.3 th term → D3 = 3rd term + 0.3(4th term - 3rd term) → D3 = 289 + 0.3(324 - 289) → D3 = 289 + 0.3 * 35 → D3 = 289 + 10.5 → D3 = 299.5 now, 70th percentile :- → k = 70/100 = 0.7 so, → p(70) = 0.7 * 10 = 7th term = 625 (Ans.)
