## Looking Normal

#### Activity Overview

This lesson involves examining multiple samples taken from a single approximately normal population.

#### Objectives

• Students will recognize that the shape of the distribution for a single sample varies from sample to sample, even when all the samples come from the same population.
• Students will recognize that the variability in shape from sample to sample decreases as sample size increases.
• Students will recognize that larger samples from an approximately normal population will more often "look" normal than will smaller samples from the same population.

#### Vocabulary

• dot plot
• histogram
• normal distribution
• normal probability plot (NPP)
• population
• sample
