**Create a Data Set**

Students will create data sets with a specified mean, median, range, and number of data values.

**Bouncing Ball Experiment **

How high does the class think a typical ball bounces (compared to its drop height) on its first bounce? Students will conduct an experiment to find out.

**Adding New Data to a Data Set **

Given a data set, students will explore how the mean changes as they add data values.

**Bowling Scores **

Students will create bowling score data sets that meet certain criteria with regard to measures of center.

**Mean Number of Fillings **

Ten people sit in a dentist's waiting room. The mean number of fillings they have in their teeth is 4, yet none of them actually have 4 fillings. Students will explain how this situation is possible.

**Forestland **

Students will examine and interpret box plots that show the percentage of forestland in 20 European countries.

**What's My Data?**

Students will create a data set that fits a given histogram and then adjust the data set to fit additional criteria.

**What's My Data 2? **

Students will create a data set that fits a given box plot and then adjust the data set to fit additional criteria.

**Compare Graphs **

Students will make a box plot and a histogram that are based on a given line plot and then compare the three graphs to decide which one best represents the data.

**Random Numbers **

What would a data set of randomly generated numbers look like when represented on a histogram? Students will find out!

**No Telephone? **

The U.S. Census Bureau provides state-by-state data about the number of households that do not have telephones. Students will examine two box plots that show census data from 1960 and 1990 and compare and analyze the data.

**Who Is Taller?**

Who is taller—the boys in the class or the girls in the class? Students will find out by separating the class height data gathered earlier into data for boys and data for girls.
