 Sample Means - Exploring Sampling Variability
 Activity Description
 mm3_160

		Students will explore sampling variability in the sample means of different random samples of a population, using data on Internet access from the U.S. Census Bureau’s American Community Survey.
 Suggested Grade Level
 7
 Approximate Time Required
 45-60 minutes
 Learning Objectives
 Students will be able to help create dot plots to represent a collection of sample means.
Students will be able to select a random sample from a population.
Students will be able to understand that sample means for different random samples of the same population will differ due to random selection.
Students will be able to understand that there is less sampling variability in the sample mean when the sample size is large than when the sample size is small.
 Materials Required
