Khan Academy: Exploring Standard Deviation 1 Module

Does standard deviation work for non-symmetrical distributions, and what does it mean? Through the use of examples, high schoolers determine the standard deviation of a variety of distributions and interpret its...

A mid-module assessment uses two multi-part questions to measure progress toward mastery on descriptive statistics standards. Each part of a question addresses a single standard to help determine mastery.

Continuing his conversation about data sets from the previous video, Sal introduces range, variance, and standard deviation as means of dispersion. Those advancing in algebra or beginning a statistics class will benefit from Sal's clear...

What if math teachers are really pirates and they want us to find x so they can get the buried treasure? A short video explains how to calculate standard deviation and variance with a step-by-step guided practice problem. The...

Video reviews the population and sample mean and variance then expands to population and sample standard deviation. Gives examples of calculating the standard deviation. [13:07]

Find the standard deviation of a set of integers. Using the formula to find the standard deviation, the instructor shows you how to apply the formula to a small set of integers.

This video demonstrates how to solve a one-step equation using division and multiplication. It also shows how to check the answer by plugging it back into the equation. [2:23]

In this statistics learning exercise, statisticians construct a stem-plot and answer questions regarding the shape of the distribution, standard deviation, and outliers.

A continuation of the Khan Academy video lesson series on identifying conic sections. This segment goes through examples that cover identifying and graphing both a circle and a parabola. [11:34]

Video explaining how the Poisson probability distribution relates to the binomial distribution. Begins explaining the derivation of the Poisson distribution by referencing an example about the number of cars passing a certain point,...
