# One Variable statistics

## Activities:

- Ping-Pong Ball Race
- Number of stars in a minute,
- How many M&M's of each color are in a package?

## Procedure for One Variable Statistics Exploration

Collect data from a one variable experience.

Example experiences to use to collect data for one variable.

*Ping-Pong Ball Race *

Time it takes to carry a ping-pong ball across the room in a teaspoon.

*Number of stars in a minute*

Time the number of stars a person can draw in one minute.

*How many of each color of M&M's are in package?*

Count the number of M&M's that each color in a package. (M&M's activity)

*Examples of what to do with the data*

- Compare the totals from different groups.
- Have everyone do the task again with their other hand and compare everyone’s right hand total against everyone’s’ left hand total.
- Have students line up on a number line, relative to their data point. Or put the data in numerical order on a number line.
- Have students put their initials on a sticky dot and place it (relative to their data point) on a grid to create a class graph for the information collected.
- Have students determine the mean, median, and mode and explain how each relates to the rest of the data points.
- Make a box and whisker plots or stem and leaf plots for the data and explain how each relates to the rest of the data points.
