#### Activity Overview

I use French fries from our cafeteria to do data analysis.
The students count the number of fries in a single serving of fries along with weighing the order.
Then measure the length and weight of a sample of individual fries.
We use the TI-Navigator™ system to collect the data from the students and redistribute the augmented lists back to the class.
Students then analyze the data to decide what a typical order of fries and a typical fry looks like.
The students then get to eat their fries.

#### Before the Activity

Students will have studied the methods used to do single variable analysis prior to this lesson.
