Abstract

Here's a project that will teach you about math as you follow some of your favorite players or teams. You'll be comparing day-to-day performance with long-term averages, and trying to determine if the "streaks" and "slumps" over shorter time periods are due to random chance or something else. When you've finished, you'll have a better understanding of some important concepts in statistical analysis and baseball.

If a player goes 0-for-20, does that mean anything? Using probability theory, how often would you expect a .275 hitter to go 0-for-20? How much can streaks be explained by luck alone, and how much are they affected by a player? As for teams, do their runs of wins and losses mean anything?

Select a group of regular players and get their game logs from ESPN.com. Look at moving averages of their batting average over 2, 3, 4 or 5 games. Estimate the probability that they would exhibit this performance based on their career and season statistics. Or do the same for teams.

Do you have specific questions about your science project? Our team of volunteer scientists can help. Our Experts won't do the work for you, but they will make suggestions, offer guidance, and help you troubleshoot.

Variations

For the team study, adjust their probability of winning by their opponents winning percentage.
