Suppose you have a Sample standard deviation of 0.393 for unemployment in USA and a Sample standard deviation of 0.260 for the crimes committed in USA. How would you compare these two? what can you observe by the two standard deviations?

(The two numbers are percentages)

The most important thing involved in comparing standard deviations is to convert them into % standard deviations. Divide the standard deviation by the average and mutliply that by 100. It is hard to directly compare two standard deviations without this conversion.

The one with the smaller standard deviation is focused more centrally around the mean of the data, whereas the one with the larger standard deviation is more spread out. Further, if you picked an element out of the group with the smaller standard deviation, you would expect it to be centrally located near the mean, and if such a selection was far from the mean, you might consider revising the mean.

The standard deviation is used to in knowing how far spread apart the set of numbers is. If you were to graph the information from the sets then you could that number from the standard deviation to express the spread of the data.
