Objective

By the end of this lesson, you will be able to apply statistics concepts to analyze chess games and make informed decisions.

Materials and Prep

• Chessboard
• Chess pieces
• Pen and paper

No prior knowledge of statistics is required for this lesson.

Activities

1. Record the outcomes of 10 chess games you play against a friend or family member.

   For each game, keep track of whether you won, lost, or drew the game.

2. Create a frequency table to display the results of your games.

   Count the number of wins, losses, and draws, and organize them in a table.

3. Calculate the percentage of wins, losses, and draws from the frequency table.

   Divide the number of wins, losses, and draws by the total number of games played, then multiply by 100 to get the percentage.

4. Create a bar graph to visually represent the results of your games.

   Use the frequency table to plot the number of wins, losses, and draws on the graph.

5. Analyze the data from your frequency table and bar graph.

   Identify any patterns or trends in your game outcomes.

Seventh Grade Talking Points
