Unit 8, Lesson 11
Estimating Population Measures of Center
Accelerated 6
Preparation
Lesson Narrative
In this lesson students calculate measures of center and variation for samples from different populations and consider the meaning of these quantities in terms of the situation (MP2). Then students use these measures to estimate a center for the associated population. Students see that when there is less variability in the data from a sample, there is reason to believe that the measure of center from a sample is a better estimate for the measure of center from a population than when a sample has greater variability (MP7).
- Calculate and interpret (orally and in writing) the mean absolute deviation of a sample.
- Generalize that an estimate for the center of a population distribution is more likely to be accurate when it is based on a random sample with less variability.
- Use the mean of a random sample to make inferences about the population, and explain (orally and in writing) the reasoning.
Let’s use samples to estimate measures of center for the population.
