WebThe TI-Nspire family handhelds will calculate two types of standard deviation: the sample standard deviation and the population standard deviation. The population standard deviation, denoted by óx, divides the calculated values by n. The sample standard deviation, denoted by Sx, uses the value n-1 as the denominator. The graphing … WebHere's how to calculate population standard deviation: Step 1: Calculate the mean of the data—this is \mu μ in the formula. Step 2: Subtract the mean from each data point. These differences are called deviations. Data points below the mean will have negative deviations, and data points above the mean will have positive deviations.
