The TI-83 Plus family of graphing calculators calculates two types of standard deviation: the standard deviation of the sample and the population standard deviation. The population standard deviation, denoted by s x, divides the calculated values by n. The sample standard deviation, denoted by Sx, uses the value n-1 as the denominator.Definition 6.3. 1: z-score. (6.3.1) z = x − μ σ. where μ = mean of the population of the x value and σ = standard deviation for the population of the x value. The z-score is normally distributed, with a mean of 0 and a standard deviation of 1. It is known as the standard normal curve. Once you have the z-score, you can look up the z-score ...Using these calculators, you can graph the bell curve.
