Major League Baseball - Dual Axis Chart and Connected Scatterplot

Dual Axis Chart of MLB Strikeouts Per Game and Pitchers Per game (Lab 4 Task 1)

In this lab we created a dual-axis chart between average strikeouts per game and pitchers per team for the MLB. Additionally, we added trend lines for each axis and a reference line for the year 1969. Upon analyzing the data, we can see that their is a strong coorelation between the number of pitchers and the average amount of strikeouts per game as years have gone on. This tends to make sense because the more pitchers participating in each game as the sport became more popular, the more likely it is have a strikeout per game. One could also argue that as the sport became more popular, pitchers refined their techniques to allow for more strikeouts. Ryan Facks - zID 2027325

Connected Scatterplot of MLB Strike Outs versus Pitchers Per Team across 1981 - 2012(Lab 4 Task 1 - Part 2)

In the second part of lab 4 part 1, we created a connected scatterplot using the MLB data provided to us by our textbook. Our resulting graph is a scatterplot with lines connecting the points where each point represents the average number of strikeouts per game on the y axis and the number of pitchers per team on the x-axis. Each point is labled with its cooresponding year and the data is filtered down to only be between the ranges of 1981 - 2012. A clear patter emerges that as the number of Pitchers Per Team increased, so too did that average number of strike outs as the years went on. We can see a dramtic shift from 2011 to 2012 with nearly a 0.5 increase of stirkeouts per game. This would imply that pitchers have really stepped their game up and are refining their craft within that year. Inversely so, maybe batters are suffering during that year and simply could not hit the ball. Ryan Facks - zID 2027325

Final Project - Chicago Divvy Bike Usage in 2019

Image
← Back to Home Chicago Divvy Bike Usage Dashboard (EAE 452 Final Project) This dashboard is used for my final project for EAE 452. This dashboard seeks to provide a spatial temporal analysis of Divvy Bike usage across Chicago in 2019. I restricted my analysis to a single full year for two main reasons. One, the Chicago data portal only has data for 2013 - 2019 and two, there are simply too many records for Tableau to handle on my computer if I include all available data (It was over 21 million records!). The dashboard is constructed with four main components; The map view of stations and their usage numbers, the trips by hour bar chart, and the total trips bar chart, and an embeded Google maps area. All four elements are connected together due to a shared data source, dashboard actions, and there are data filters to further drill down on the data. For example, you can select a particular day of the week an...

Chicago Private School Dashboard and USA Child Poverty Dashboard (Lab 7 - Week 8)

Image
← Back to Home Chicago Private School Enrollment (Lab 7 - Dashboard 1) This dashboard was created using Chicago Data Portal public data on the enrollment status of private schools within Cook County Illinois. The dashboard consists of four main components which are a map symbolized by each town, a map showing enrollment numbers that is symbolized by color and proportional size, a listing of all address locations, and a Google Maps viewer that shows the satellite view of a selected location. All of the elements of this dashboard are tied together so if you click on a data point in one, it will zoom-to and/or highlight the corresponding data point in all of the other dashboard components. This dashboard seeked to employ our understanding of color and color blind friendly map making by using the website ColorBrewer2.org to find a color pallete that is suitable for the most amount of audiences. Addtionally, I ...
