Unit 6, Lesson 13# Describing the Variability Using the Interquartile Range (IQR)

EngageNY 45 min(s)

Students describe the unit of measurement for observations in a data set. Students calculate the median of the data and describe the variability in the data by calculating the interquartile range. Students develop understanding of statistical variability, in particular recognizing that a measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how the values in the data set vary. Students are also expected to summarize numerical data sets in relation to their context.
