Week 4

 

 


 

This past week, Dr. Posta tasked me with again building a simple model to predict an upcoming match between the Phoenix Rising and Detroit City FC. For this week, there was a focus on using Excel formulas while building this model. Once again, using stats from the past 10 games, I calculated expected goals for both teams heading into this match. Using that xG stat, I calculated the probabilities of several different possible outcomes of the game.

Ultimately, the model expected the Phoenix Rising to win 29% of the time, lose 26% of the time, and draw the remaining 46 percent of the time, with the single most probable outcome being a 1-1 draw 12% of the time.

The actual outcome of the match was a 5-0 blowout by the Phoenix Rising. The model only expects a 5-0 outcome 0.00006 percent of the time, so the result of this match was very much a statistical anomaly. This is what brings us to the next stage of our research project, data collection.

For this project, we are going to be collecting a lot of data. While it will be a long process, it is very much necessary to drown out the “noise” from statistical outliers, such as this most recent Phoenix Rising match, that would otherwise skew our predictions.  This week, I will be meeting not only with Dr. Posta, but the rest of the team working on this project. So I am excited to get to meet the rest of the team and continue making progress on our project.

    Hi Steven,

    It's really interesting what your model expected versus the actual outcome. I don't watch a lot of soccer but I imagine 5-0 outcome is pretty big no matter what. I find collecting data to be one of easier task to do in science. I hope that you get all the data you need with the best outcomes.

        This week I continued to refine my research project with the help of Josh. I have a pretty good idea of the direction that I am headed with this project, but we are still tweaking things around. Josh got me started playing around with the EKG so I can start familiarizing myself with it. We ran tests on a few volunteers in the lab just to get familiar with the equipment/readings before moving on to testing plants. I have an exam for my math class on Friday and then an exam for my physics class this coming Monday, so I am shifting my focus to that for the next few days. I am very much looking forward to getting back in the lab and continuing to make headway on this project once these exams are behind me.

  My tomato plants are coming along slowly. Perhaps too slowly? While I feel handcuffed, unable to begin my research until the plants are mature enough, we are putting this time to good use. We are having issues exporting data from the LabQuest 2 into the computer. For whatever reason, the data gets distorted during the process of exporting/importing. We are trying to figure out what is causing this issue while also coming up with plans in case we can’t get the LabQuest 2 to play nice (manually entering the data points does not sound like fun given how much raw data the LabQuest 2 gives). Hopefully, it will not come to that.   Outside of the lab, things are going well in my classes. These next few days will be intense as I will be spending most of time preparing for midterms. I look forward to getting back in the lab once that is over with.
