This Instructional Activity is a part of the Lesson 7, Unit 6, Grade 8. English language learners need the chance to practice using the terms clusters and outliers in both oral and written contexts. Sentence frames may be useful for students to communicate initial ideas. Spend a few minutes introducing the meaning of the terms clusters and outliers in the context of scatter plots. Consider asking students to sketch a scatter plot that has an outlier and a scatter plot that has two clusters as a way of checking their understanding of these terms before moving on to the exercises that follow. In addition to looking for a general pattern in a scatter plot, you should also look for other interesting features that might help you understand the relationship between two variables.
