23 kwi 2021 · The sample variance tells us how spread out the values are in a given sample. Typically denoted as s2, it is calculated as: s2 = Σ (xi – x)2 / (n-1) where: x: sample mean. xi: the ith value in the sample. n: the sample size. The following step-by-step example shows how to calculate the sample variance for the following sample:
How is variance calculated on the TI-84 Plus Family of graphing calculators? The TI-84 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 ...
