I like doing statistical ****** ysis for two primary reasons. There are two main biases that it combats and we are all prey to those biases at one time or another. The first form of bias is what I would call immediacy bias. A great example of that is the string of short starts that the Astros are currently going through. The temptation is to ****** ume that this has been constant throughout the season when that is almost never the case. There are ebbs and flows to these things, so looking at overall numbers can help us combat that bias.
The second bias is a local bias. We watch the Astros. Some of us watch them religiously. So, when we are watching one team 162 times a season and the other teams maybe a handful of times, it is easy to look at what your local group is doing and ****** ume that it is either really good or really bad. We simply don't have anything to compare it to. This becomes important when we are looking at relative strengths and weaknesses of a team. This can come into play in terms of game to game strategy or long-term questions about how the team should be structured.
We call this the lab because I like to start with observations that can be formed into a testable hypothesis. In this case, the hypothesis is that the Astros overly rely on their bullpen for innings because their starters do not go deep enough into games. We can test that simply by comparing them with the rest of the American League to see if that is true comparatively. We will start with the starting pitchers only in terms of innings pitched and ERA.
