      99.72% (49.86 X 2) of the data fall between mean ( 3 SD. If the SD is close to the mean score, the SD is large. Whenever the smallest or largest observation is less than a standard deviation from the mean, this is evidence of server skew. (4) The Coefficient of Variation (CV) CV = 100 (SD/M) The CV expresses the SD as percentage of the mean value.
