 a measure of the degree of dispersion of data Explanation:If you look standard deviation in online dictionaries, I think the most commonly used terms are "measure" (指標）, "dispersion" （ばらつき）. So while there is a tiny bit of variation in the wording of the definitions, I think this would work just fine. --------------------------------------------------Note added at 9 mins (2008-04-24 02:48:21 GMT)--------------------------------------------------If you wanted to include 示す、then maybe "a measure indicating the degree of dispersion of data".
