How Do You Find the Standard Deviation of a Data Set?

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...

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.

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,...

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.

Students learn how to calculate the standard deviation by hand. Detailed examples that explore how to use the standard deviation formula are included.

This tutorial illustrates the entire process of finding the standard deviation of a data set. [6:17]
