Unit 6, Lesson 8# Variability in a Data Distribution

EngageNY 45 min(s)

Students interpret the mean of a data set as a typical value. Students compare and contrast two small data sets that have the same mean but differ in variability. Students also consider variability (spread) when describing a data distribution. Students informally evaluate how precise the mean is as an indicator of a typical value for a distribution, based on the variability in the data.
