## Data Analysis and Probability

#### Activity Overview

Students explore the basics in data analysis and probability.

#### Before the Activity

• See the attached PDF file for detailed instructions for this activity
• Print student activity sheets for each separate section: Spin Me Along pg 108-109, Tiles in a Bag pg 114, Number Cube Sums pg 118, Analyzing Number Cube Sums pg 121, Picturing Probabilities of Number Cube Sums pg 127, and An Average Lunch? pg 131.

• #### During the Activity

Distribute the page to the class.

Spin Me Along:

• Explore probability and patterns in fractions, decimals, and percents by spinning three spinners and recording and analyzing the result

• Tiles in a Bag:
• Explore probability and patterns in fractions, decimals, and percents by drawing tiles out of a bag and recording and analyzing the results

• Number Cube Sums:
• Explore experimental probability and patterns in fractions, decimals, and percents by rolling two number cubes and recording and analyzing the sums that come up

• Analyzing Number Cube Sums:
• Extend the understanding of theoretical probability and patterns, using number cubes
• Build awareness that a fraction and its decimal and percent representation on the calculator are close, but not necessarily equal

• Picturing Probabilities of Number Cube Sums:
• Use ideas of ratio and proportion to investigate various ways to make a circle graph
• Graph the probabilities of the different sums that can be generated with two number cubes

• An Average Lunch?:
• Explore the meaning of the average (mean) value for a set of data
• #### After the Activity

• Review student results
• As a class, discuss questions that appeared to be more challenging
• Re-teach concepts as necessary
