Materials and Prep

• Chessboard
• Chess pieces
• Pen and paper
• Calculator (optional)

No prior knowledge of statistics is required.

Activities

1. Record and analyze your chess game results:

   • Play at least 5 chess games against opponents of varying skill levels.
   • Record the outcome of each game (win, lose, or draw).
   • Create a tally chart to keep track of the results.
   • Convert the tally chart into a bar graph to visualize the data.

2. Calculate your win percentage:

   • Add up the number of wins and divide it by the total number of games played.
   • Multiply the result by 100 to get your win percentage.

3. Analyze the win percentage:

   • Compare your win percentage to the average win percentage of chess players at your grade level.
   • Discuss possible reasons for differences in win percentages.
   • Identify areas of improvement to increase your win percentage.

4. Plan and implement strategies:

   • Based on your analysis, come up with strategies to improve your chess performance.
   • Implement these strategies in future games and record the results.
   • Analyze the impact of the strategies on your win percentage.
