Best Answer: It is possible for the standard deviation to be greater than the mean, even if all data points are positive numbers. However, the only way for this to happen is for most, if not all, data points to be at the extremes (with one extreme much greater in magnitude than the other) and nothing near the average.
You are right. Standard deviation is the measure of dispersion away from the mean, or average, value. It tells you how likely it is that a randomly chosen sample will be at or near the mean. Less dispersion (lower standard deviation) shows that things are more alike and mostly like the mean. just now. Report Abuse. The standard deviation is a measure of the spread of a normally distributed population. Knowing it and the mean you can calculate the proportion of the population having any particular value of the measured variable.
