“Where were you most effective getting work done for “Math in the School Program?”

Let’s take a look at our results………....

Teaching Data Analysis

Planning for Focused Instruction:

“The amount of statistical information available to help make decisions in business, politics, research, and everyday life is staggering.”

Such as: Consumer surveys guide the development and marketing

of products. Experiments evaluate the safety and efficacy of new

medical treatments. Statistics sway public opinion on issues and represent--or

misrepresent--the quality and effectiveness of commercial products.

Planning for Focused Instruction:

“Through experiences with the collection and analysis of data, students learn how to interpret such information.”

“Young children will not develop statistical reasoning if it is not included in the curriculum. Work in data analysis and probability offers a natural way for students to connect mathematics with other school subjects and with everyday experiences.” (NCTM)

Objective and Rational for Teaching Data Analysis:

Therefore, students should be able to…..

formulate questions that can be addressed with data and collect, organize, and display relevant data to answer them;

select and use appropriate statistical methods to analyze data;

develop and evaluate inferences and predictions that are based on data (NCTM).

Objective and Rational for Teaching Data Analysis:

In other words, students should be able to…

Collect data (surveys and experiments)Display data (graphs – i.e. bar graph)Analyze data (find landmarks – i.e. mean)

○ Also includes: ‘data sense’ and being able to identify misleading information

Let’s try an activity together:Landmark Shark Game (EDM – 2004)Objective: TSW find range, median, mode, and mean of a set of numbers.

Materials: 1 deck of cards, 1 each of range, median, mode cards (for each player), score sheet (2-3 players)

Directions:

1) The dealer shuffles and deals 5 cards facedown to each player. Each player puts cards in order from smallest to largest.

2) There are 3 ways to score points: range, median, or mode is used as the player’s score….each player decides which of the 3 landmarks will yield the highest score for their hand. They indicate their choice by showing the dealer this card.

3) Players can try and improve their score by exchanging up to 3 of their 5 cards for new ones, but the landmark card stays.

4) Their scores are then recorded, but bonus points may be earned at this point. Each player calculates their mean of their cards and then records (to the nearest tenth) their points and add those points to their score sheet as well.

5) Repeat steps #1-4 for each round. The winner is the one with the highest score after 5 total rounds.

Summary: Helping students see the bigger picture and

applying deeper connections to data analysis and the real world.
