Find the range for the set of data given in problems 1) , 2) and 3).
1)
Range = maximum value – minimum value
607- 117 = 490
2)
Range = maximum value – minimum value
35- 15 = 20
3)
Range = maximum value – minimum value
74 - 70 = 4
Find the standard deviation from problems 4) to 5). Round to one more place than the data.
4) 14, 14, 10, 7, 14, 14, 13, 19, 15, 15
