## Lesson Snapshot

#### Understanding

Numbers used in describing a characteristic of the population (typically measures of center, spread, maximum and minimum) can be estimated by calculating the corresponding statistic using the data in the sample.

### What to look for

To understand how a sampling process works, students need to understand the difference between a population (the large set of interest) and a sample (a subset of that population).

### Sample Assessment

A survey given to some of the people at the mall on Friday night indicated that shopping hours at the mall should be extended. What is the population for this sample?
