Unit 3, Lesson 14
Outliers
Integrated Math 1
Preparation
Lesson Narrative
Students are introduced to outliers, investigate their source, make decisions about excluding them from the data set, and examine how the presence of outliers impacts measures of center and measures of variability.
When students analyze data in the context of a problem to determine whether or not to exclude an outlier, they are reasoning abstractly and quantitatively (MP2). This reasoning process is also an aspect of mathematical modeling (MP4).
- Describe (orally and in writing) how outliers impact measure of center and measures of variability.
- Determine (in writing) when values are considered outliers, investigate their source, and determine if they should be excluded from the data.
