I found a standard deviation equal to 937.5, this can be possible?

Question

i am doing data anlysis in spss and found a standard deviation high somehow; I would like to know if there is a limit value that the standard value can not be greater than

Answer 1

Yes. A standard deviation can be any positive value. If you divide it by the mean you should get a fraction every time. For example, if the mean population of a group of towns was 10,000 people, the mean and standard deviation would imply quite a modest variation: 10,000±937.5. But if you check the SD against the mean and you don’t get a fraction you have made a mistake (for example, you may accidentally have calculated the variance which is the square of the SD).
