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 lesson has learners collect different data sets and calculate mean, range, and standard deviation. They compare their calculations and look for connections between the...

Through a series of problems, learners determine the variability of a data set by looking at the deviations from the mean. Estimating means of larger data sets presented in histograms and providing a way to calculate an estimate round...

Who is more accurate, boys or girls? Scholars kick a ball in a goal and record makes and misses. They then analyze the data using standard deviation and variance. Their final task is to make a comparison between the data from boys and...

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. 

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...

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...

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.
