Is There Such a Thing as Streakiness in Baseball? *
|Time Required||Average (6-10 days)|
|Prerequisites||Basic knowledge of Microsoft Excel and statistics|
|Material Availability||Readily Available|
|Cost||Very Low (under $20)|
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.

StatisticianStatisticians use the power of math and probability theory to answer questions that affect the lives of millions of people. They tell educators which teaching method works best, tell policy-makers what levels of pesticides are acceptable in fresh fruit, tell doctors which treatment works best, and tell builders which type of paint is the most durable. They are employed in virtually every type of industry imaginable, from engineering, manufacturing, and medicine to animal science, food production, transportation, and education. Everybody needs a statistician! Read more
ActuaryLife is full of risks to both people and property. Actuaries predict the chances that future negative events will occur in a person's life, and then think of ways to reduce those chances, or reduce the impact of those negative events. Actuaries help bring peace of mind to both families and to businesses. Read more
Math TeacherMath teachers love mathematics and understand it well, but much more than that, they enjoy sharing their enthusiasm for the language of numbers with students. They use a variety of tools and techniques to help students grasp abstract concepts and show them that math describes the world around them. By helping students conquer fears and anxieties about math, teachers can open up many science and technology career possibilities for students. Teachers make a difference that lasts a lifetime!
