23 kwi 2021 · How to Find Sample Variance on a TI-84 Calculator. by Zach Bobbitt April 23, 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.
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 sx, divides the calculated values by n.
