The numbers of days of rain per month in seattle, for a period of twelve months, are: 18, 14, 16, 14, 12, 9, 5, 0, 7, 13, 18, 17

what is the range of the data values?

a. 12

b. 14

c. 18

d. 1

 C. 18

Step-by-step explanation:

We know that the range of a data set is the difference between the maximum data value and the minimum data value.

Given : The numbers of days of rain per month in Seattle, for a period of twelve months, are:

18, 14, 16, 14, 12, 9, 5, 0, 7, 13, 18, 17

Maximum data value = 18

Minimum data value = 0

Then , the range of the data set will be :-

Range = 18-0 =18

Hence, the range of the data values =18

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
