Unit 6, Lesson 7
Observing More Patterns in Scatter Plots
Grade 8
Preparation
Lesson Narrative
In this lesson, students see non-linear associations for the first time and use a Card Sort to distinguish linear and non-linear associations. They visually identify clusters in data and explain that this may be caused by subgroups within a data set exhibiting different trends. At this level, students rely on the structure of visual patterns in scatter plots (MP7) to recognize non-linear associations and clustering rather than quantitative tools.
- Categorize data sets, and describe (orally) the properties used to create categories.
- Describe (orally) features of data on scatter plots, including “linear” and “non-linear association” and “clustering,” using informal language.
- Explain (orally) what might cause a non-linear association or clustering of data points in context.
Let's look for other patterns in data.
Required Preparation
Print and cut up cards from the “Scatter Plot City” blackline master. Prepare 1 set of cards for every student.
