  2. For the following Data : • 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 • Find • Standard deviation • ∑(X)^2 = 3795 • (∑x)^2 = 64009 • S = 6.5

  3. 2) IQR IQR = Q3-Q1 Q1 = percentile 25% Q3 = percentile 75% ………………………… Percentile 25% i = (25/100) * 22 = 5.5 = 6 ….. Percentile 25% = 6 ………………………… Percentile 75% i = (75/100)*22 = 16.5 = 17 …. Percentile 75% = 17 ……………………….. IQR = 17-6 = 11
