A Lesson In Standard Deviation

Don't be content with just a standard resource on standard deviation. Scholars first take several sets of data with the same mean and identify the median, range, and interquartile range. They then use calculators to determine the...

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 meaning. Problems require...

How does the range of data affect standard deviation? A well-designed instructional activity has learners collect different data sets and calculate mean, range, and standard deviation. They compare their calculations and look for...

In this standard deviation instructional activity, learners identify and complete 3 different problems that include determining the standard deviation illustrated. First, they label the bell-shaped curve on each graph with the given...

Examine the relationship between the standard deviation and margin of error with a video that begins by calculating the margin of errors given different standard deviations. Through the calculations, learners recognize that increasing...

What did the math book say to the psychology book? I have a lot of problems. A helpful video covers how to calculate the margin of error with various standard deviation numbers. 

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 formula is...

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. 

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

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.
