Streaks in Baseball: A Mystery?

Streaks in Baseball: A Mystery? | Science Fair Projects | STEM Projects
Have you ever noticed that baseball teams sometimes go on winning or losing streaks? We wanted to find out if this was just luck or something else. So, we looked at the National League in 2001 and compared the streak frequencies to two artificial seasons. We found that the streak frequencies were significantly different from random chance, suggesting that other factors are at play.


The hypothesis is that factors other than random chance affect the frequency of win/loss streaks in baseball.

Method & Materials

You will compare the streak frequencies of the National League in 2001 to two artificial seasons. One will be a Monte Carlo simulation using a coin flip and the other will be a season based on calculated streak frequencies.
You will need data from the National League in 2001, a coin, and a calculator.


Our experiment showed that the distribution and frequency of streaks in Major League Baseball is not purely random. Factors contributing deviation from randomness could include pitcher rotation or playing games in series.

Why do this project?

This science project is unique because it looks at a phenomenon that is often taken for granted and tries to explain it.

Also Consider

Experiment variations to consider include looking at different leagues or different years.
