62 67 69 72 75 60 58 86 74 68

56 67 82 88 90 54 67 65 64 68

74 65 58 75 67 65 66 64 45 64

Find the upper and lower quartiles

**drwls**, Saturday, June 20, 2009 at 6:20amRewrite the list in ascending order, and then divide the list into four parts. That will tell you the quartile boundaries.

45 54 56 58 58 60 62

64 64 65 65 65 66 67 67

67 67 68 68 69 72 74 74

75 75 82 86 88 90

Q2 = 67 (divides into upper and lower halves)

-------------

Q1 = 64 (median of lower half)

Q3 = 74 (median of upper half)
