Standard Deviation Of Frequency Distribution TI84. by Kent Learning Commons on Jul 17, 2012. image/svg+xml.

In general, you'll need to know two quantiles of a normal distribution in order to determine $\mu$ and $\sigma.$. Here is an example based roughly on the part of the Empirical Rule that says about 68% of the probability under a normal curve lies between $\mu \pm \sigma.$ Thus quantiles .16 and .84 of $\mathsf{Norm}(\mu=100,\sigma=15)$ are roughly at 85 and 115.Shows how to use the TI-83 or TI-84 to calculate basic summary statistics including mean, standard deviation, etc.Find the variance.
