The Baseball Calculator Webquest

Computer Class 611/841

Mr. Penza, Instructor


A Technology Plan with elements of Mathematical Thinking,

Microsoft Excel, and Baseball Stat Calculation.

Designed for a Middle to High School classroom.


The NCTM Framework Standards employed:

        Develop fluency in operations with real numbers, vectors, and matrices, using mental computation or paper-and-pencil calculations for simple cases and technology for more-complicated cases.

        Judge the reasonableness of numerical computations and their results

        Draw reasonable conclusions about a situation being modeled

        Compute basic statistics and understand the distinction between a statistic and a parameter.


Lesson Objective: To introduce the student to the relationship of MLB batting statistics, and then incorporate this understanding by applying formula concepts and analysis in a Microsoft Excel Spreadsheet.




1. Click on the following link and read the presentation.


Text Box:

2. Now click on this link. This is the Los Angeles Dodgers web site. Search around to find the team statistics page. You will need this page to gather input for your calculations. Print out the page so you can refer back.


3. Now click the Calculator on the Navigator bar (left). Try out some numbers to see how it works.

4. See if you can figure out how the Calculator is figuring each of the OUTPUT values.


5. Are some of your calculated values not exactly correct? Why do you think that is?


6. Once you are comfortable with the statistics, click on the Submit button (left), answer the questions and submit to your instructor.
