Khan Academy: Finding the Mean and Standard Deviation of a Binomial Random Variable

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...

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...

Good news! We only have a half day of school this morning. Granted, we have the other half this afternoon. The video is a visual representation of the definitions of mean and standard deviation. 

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...

Finding the variance and standard deviation of a discrete random variable.

Deviation is normal in the world of statistics. Viewers first learn about the normal distribution curve in an informative video. They then watch as the narrator calculates standard deviation by hand and using spreadsheets.

This lesson demonstrates to students how to use standard deviation to better understand a set of data. Students use standard deviation to determine the general pattern or shape of a given set of data to draw more reliable conclusions.

This video demonstrates how to take linear equations written in either slope-intercept form or point-slope form and rewrite them in standard form of a linear equation. Right-click on the square at the bottom right for a full-screen view....

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.

Explanation of frequency distributions, mean, standard deviations, and variance including a Java Applet.
