So, what does Hollerith's tabulating machine have to do with scoring baseball games? Everything!

The purpose of Hollerith's machine was to compile data. A baseball scorecard contains a wealth of data that lends itself to compilation. After compilation, these data can be analyzed. Part of the majesty of the sport is how well it can be documented. Baseball scorekeeping is our in to the study of statistics.

Data Collection
Our curriculum relies heavily on students working with data. Whether we are working with compiled data sets or collecting data of our own, getting down to the numbers is an everyday activity.

Scoring ball games provides a wealth of data. At first, we compile the statistics for the game. For individuals: ABs, Runs, Hits, Walks, Strike Outs, RBIs, Put Outs, Assists, and Errors. Then we calculate the team statistics.

Later, we began adding other statistics to our calculations, namely, pitching statistics. I suggest getting a copy of the rules to help determine what is a save, passed ball, etc. Having a computer available for students to look up rules on the Internet is an effective way to have the students engaged.

Once students are comfortable with scoring and the after-game tabulation, the fun really begins. We learn in our studies that the larger the sample, the more accurate the analysis. We keep track of a series of games. Usually these are three-game sets. We compile the batting and pitching statistics for both teams over three games and calculate batting averages, ERA, etc.

Students begin seeing consistencies and inconsistencies in the data they are collecting. Some pitchers have stolen bases against them, others do not. Some players get on base frequently and others strike out consistently.

It is at this point you can capture the students' interest in what they are doing. It would be difficult to score every game, but the data is available online, in the newspaper, and in weekly publications. Set the stage for on-going learning by challenging your students.
