Describing Data

In this unit, students visualize data using dot plots, histograms, and box plots, as well as calculate measures of center and spread.

Section 1: Visualizing Data (Lessons 1–6)

• Create dot plots and histograms to visualize data.

• Informally describe and compare data sets.

Section 2: Mean and MAD (Lessons 7–10 + Practice Day + Quiz)

• Calculate the mean and mean absolute deviation (MAD) of a data set.

• Use mean and MAD to describe and compare data sets.

Section 3: Median and IQR (Lessons 11–16 + Practice Day)

• Compare and contrast the mean and median as measures of center.

• Calculate the quartiles, interquartile range (IQR), and range of a data set.

• Create box plots to visualize data.

• Use median and IQR to describe and compare data sets.
