This project taught me how math can be used to study real-world systems. Starting off with improvements, my data could have been improved by being collected over the period of several days. This would have made my data have less external variables as it would be the average of a week. This project connects to my English and PBL class as in both of them, we have to collect data and analyze them in different ways, with English having us write a report and PBL having us improve a product we are designing. The global issue my project connects to is the issue of sustainable transportation and Taiwan's issue of Youbike's unavailability at certain stations and times. Youbike could collect data on their stations and have people redistribute the bikes over different stations at different times so people can find bikes more easily. One mistake I made was on the checklist (for example, inverse translations and domain). I got a few concepts mixed up, but the feedback from the teacher helped me understand where I went wrong and how to correct it. The feedback also helped me to use quadratic regression in Desmos. I also needed to make sure that the predictions I write/say actually make sense in real life. Comparing the scatter plot and quadratic equation, the scatter plot showed the recorded data, while the quadratic plot showed a general trend. I think the scatter plot is better because my quadratic model doesn't show the highs and lows of the availability of Youbikes at certain times. It just shows the midpoint. With this project, I improved my data analysis skills. In the future, I want to be able to collect a bit more data to make the findings accurate and compare my predictions with real data. There are three specific changes I would make to improve my project. First, I would collect data over several days instead of only one day. This would reduce the effect of outliers and make my results more reliable. Second, I would collect data from more Youbike stations in different areas of Taipei. This would help to compare how bike availability changes depending on the location. Third, I would collect data at more frequent intervals and record/research more factors such as weather, weekends, and holidays. These factors could affect the highs and lows of the data I collect. This project connects to my English and PBL assignments. In English, my annotated bibliography connects to this project because I had to collect information from different research papers and summarize the important points. This is similar to the math project, as I had to collect data about YouBike availability and analyze it to understand patterns. Both assignments require me to organize information and explain what I learned from it. In PBL, our seed shaker experiments connect to this project because we had to collect data from experiments and interpret the results. This is similar to my Youbike project, where I collected data and used graphs to understand a real-world system. Both projects showed me how collecting and analyzing data can solve problems. In the Netherlands, cycling is a common form of transportation. People may depend on bicycles for their everyday journeys, so an empty bike station would affect their commutes. My theory of change is that if bike-sharing companies collect data and analyze it, they can predict which stations will need more bikes. Workers could then redistribute bikes before shortages happen. This would make bike-sharing more reliable, and more people would use sustainable transportation instead of cars. Speaking of the perspective of the workers responsible for redistributing bikes. Moving bikes constantly might solve shortages, but it could also increase costs and create more work. This helped me understand that solving a transportation problem is not only about making bikes available; it is also about considering the needs of everyone involved. This project helped me use my math skills from previous classes, especially graphing equations and understanding quadratic functions. I used these skills to create a quadratic model of YouBike availability. Instead of using only individual data points, I was able to use an equation to represent the general pattern of the data. During this project, I improved my ability to organize and collect data. I also learned that analyzing data takes time, and I should stop rushing to the conclusion. One area I still need to improve is checking my work more carefully. In this project, I made some mistakes when graphing my equation. In the future, I plan to check my equations and graphs more carefully and compare them to original data before using them to make predictions. During our peer feedback sessions, I received suggestions from classmates about how to improve my project. One suggestion was to create an equation to represent my data instead of only showing a scatter plot. I used this feedback by adding a quadratic regression equation to my project. This helped me meet all the requirements for the assignment. In the future, I might study something related to biology. This project helped me understand how data collection and analysis can be useful in scientific research. Biologists have to collect data from experiments and observations and understand the patterns that come in them. This is similar to what I did for my Youbike project.
