The dispersion of values about the mean is predictable and can be Note that a gate consisting of ±1SD accounts for 68% of the distribution or 68% of the area under the curve, ±.. What is the definition of standard deviation? Standard Deviation is a statistical tool that is used widely by statisticians, economists, financial investors, mathematicians, and government officials Standard deviation is a widely used measure of the variability ordispersion, being algebraically more tractable This means that most men (about 68 percent, assuming a normal distribution) have a..

Standard deviation just tells, how much data is deviating from its mean value. If just consider standard deviation then standard deviation gives a range around mean, and in that range 68% of.. How mean and standard deviation relate to the Empirical Rule (68%-95%-99.7% rule). Using the empirical rule (or 68-95-99.7 rule) to estimate probabilities for normal distributions Practice this lesson..
