How to Calculate Margin of Error and Standard Deviation

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...

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...

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. 

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.

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.

If you've always wanted to know more about spreadsheets, here's a perfect resource for you. A self-paced tutorial introduces how to autofill and copy formulas in a Google sheet or Excel spreadsheet. It also shows users how to find range,...

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

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]

To recall or not to recall, that is the question. Using provided data, pupils calculate the percent of people that may fall ill on average. The scholars determine the standard deviation based upon the mean and the empirical rule,...
