The following represent a sample of the data science work I have done in classes. Each assignment was limited in length and scope for grading purposes, so each by itself only represents a little of what I can produce. All pdf, webpages, presentations and web applications are easily modified and updated with new data by re-running the reports using Rstudio statistical software, or in some cases, selecting new user input on the fly. Throughout these courses, I have been introduced to and utilized web scraping, apis, clustering analysis, statistical models, flexible reports, presentations and web applications, prediction study designs, and forecasting methods using Rstudio.

  1. I developed a web application for visualizing hockey player statistics. The user selects a comparative statistic and as many players as desired for comparison on that statistic. A graph is displayed for the entire 2015-2016 season showing the progress of each player on that statistic over the season. I also created a brief pitch presentation for using the app.

  2. I used a predictive tree, random forest, boosted model, and a combination of these models to determine solely from sensor data whether weightlifters were performing certain exercises correctly or not. This project involved cleaning a very messy data set with several high leverage outliers, removing the effects of missing values, and separating the data set into training and testing sets for model development and testing. My eventual model predicted 20/20 test observations correctly. My project was formed into a webpage.

  3. I composed a report performing a multivariable regression analysis comparing gas mileage of manual and automatic transmission cars. The report demonstrates that a naïve analysis assuming completely independent regressors comes to the incorrect conclusion that manual transmission cars outperform automatic transmission cars in mileage.

  4. I downloaded and analyzed Kaggle.com data for Minneapolis crime out of curiosity last summer. I created some exploratory plots and hinted at some future analysis that could be done with more time. The results are on this webpage.

  5. I wrote a webpage report outlining the economic and physical toll of weather events based on historical weather data, and presented graphs supporting these claims.

  6. I developed a brief Fitbit step analysis webpage for activity of a user.

  7. I created a brief pdf report analyzing the effect of vitamin C intake on tooth growth.
