      Therefore, the standard deviation is 2. In this case 100% of the values in the population are at one standard deviation of the mean. The standard deviation is the most common measure of statistical dispersion, measuring how widely spread the values in a data set are. If the data points are close to the mean, then the standard deviation is small.

      Suppose you want to graph a normally distributed population with a mean of 50 and a standard deviation of 4. Depending on the calculator you have, get to the screen that allows you to enter your function. Once you are on the right screen, type the following on the appropriate place for your calculator. 1/(4( (2())*e^(-0.5*(x - 50)^2/4^2).

      From table or calculator the 90th percentile for standard normal distribution is at z=1.2816. So answer is 90 + 1.2816*38 mg/dL =138.7 mg/dL Suppose that the “abnormal range” is defined to be glucose levels which are 1.5 standard deviations above the mean or 1.5 standard deviations below the mean.

      Calculating the Standard Deviation. If x is a number, then the difference "x - mean" is called its deviation. In a data set, there are as many deviations as there are items in the data set. The deviations are used to calculate the standard deviation. If the numbers belong to a population, in symbols a deviation is x − μ .
