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.

Even though this assignment is brought to you by Physics Lab Online, it is best used as a math practice. Middle schoolers calculate the range, mean, mode, and median for a list of eight different paper clip densities. They analyze...

Learners are introduced to the concepts of the normal curve, skewness and the standard deviation. They discuss how the normal distribution has been used and misused to support conclusions.

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

Is baseball really the road to riches? Here, statisticians look at salary data from baseball players and use variance to measure the spread of the data to more accurately answer that question. Note: The salary data provided is from 1994,...

Students use the computer and S'COOL data for statistical analysis.

Students compute the standard deviation for a given set of data. In this measuring dispersion lesson, students compute the mean, and then the distance from the mean for each data point. They find the standard deviation of the data.
