This lesson involves representing distributions of data using boxplots.
Center and Spread
Students will recognize that the mean and standard deviation (SD) and the median and interquartile range (IQR) are two ways to measure center and spread.
Center of Mass
Students will identify and interpret the mean geometrically as the location of the coins on the ruler such that the sum of the distances on either side of the mean is the same.
This lesson involves the interpretation of different types of histograms: frequency histograms, relative frequency histograms, and density histograms.
This lesson involves analyzing three parallel boxplots.
SD: How Far is Typical?
This lesson involves gaining a basic understanding of what standard deviation is measuring by examining the location of data around the mean.
SD: Measure of Spread
This lesson is intended as an introductory activity to the concept of standard deviation.
