Listed below are the numbers of hurricanes that occurred in each year in a certain region. The data are listed in order by year.
Find the range, variance, and standard deviation for the given sample data. Include appropriate units in the results. What important feature of the data is not revealed by any of the measures of variation? 1010 1717 1010 1616 11 33 88 55 44 44 1717 55 88 1717 The range of the sample data is 1616 hurricanes.hurricanes.

The variance of the sample data is 30.330.3 hurricanes squared .hurricanes2. (Round to one decimal place as needed.) What important feature of the data is not revealed through the different measures of variation? A. The measures of variation do not reveal the difference between the largest number of hurricanes and the smallest number of hurricanes in the data. B. The measures of variation reveal nothing about how the numbers of hurricanes are spread. C. The measures of variation reveal nothing about the pattern over time. D. The measures of variation reveal no information about the scale of the data.
Answer: C. The measures of variation reveal nothing about the pattern over time.
Step-by-step explanation:
Given the following :
10 17 10 16 11 3 8 5 4 4 17 5 8 17
Range of hurricane data = 16
The standard deviation of sample data = 5.5 hurricanes
The variance of the sample data is 30.3 hurricane^2.
The measures of variation described above only shows the spread of the hurricane such as the range, that is the highest and lowest recorded.
The variance explains how spread out the data is and the standard deviation explains how values of a data differs from the mean value. The data fails to give time related information or pattern.
