For this project, each group was to collect data from subjects about their gait. With this data, we were to formulate a predictive model. My group used the data we collected from each of us to create an equation that would predict height. After creating this model, we made a detailed report and mini presentation compiling everything that we recorded.
Here is the report:
Here is the mini presentation:
Concepts: Gait - a person's manner of walking; we looked at each subject's gait in order to create a predictive model and learn more about what determines gait Frequency - the number of occurrences of a repeating event per unit of time; we used the frequency of each subject's steps to create a predictive model for height Accelerometer - an instrument that measures acceleration; we used an app on our phone called Physics ToolBox Accelerometer that collected our acceleration while we walked on an X, Y, and Z plane Dynamicity - constant change, activity, or progress; this was seen in the steps of our subjects Metric - a system of measurement; in order to be more accurate and to use scientific quantities we used the metric system for our units Model - a description of observed or predicted behavior of some system; we created a model to predict height of subjects using their leg length Symmetry - two things being exactly similar facing each other on or around an axis; it is the quantification of differences between the left-foot and right-foot steps of the subject for our project Variability - lack of consistency or a fixed pattern; we used it to describe the fluctuations in data from one stride to the next Standard deviation - a quantity calculated to indicate the extent of deviation for the group as a whole; we used the standard deviation of our subjects' heights in order to predict height for anyone
Reflection: This project was difficult for me. I didn't understand what we were supposed to do and was confused about how to create a predictive model. I didn't talk to my group as much as I should have throughout the project to help me understand. Next time when I am confused about something, I will make sure to ask my group and anyone else to help me understand it. I will also make sure that I understand the project at the beginning. This will help me save time and prevent me and my group from having to do more work at the end of the project. For this project, I didn't understand it as well as I could have, so I had to take more time throughout the project to figure out what I needed to do. I think I did a good job getting complete data. I made sure that we tested our subjects more than one time, and that we recorded their height, weight, shoe size, leg length, and the weight of the backpack. This helped us have a more detailed report. I also did a good job taking less of a leadership role on this project, which I have said I wanted to do in past projects. I let my group lead more in what we needed to do and when we needed to do it. Overall, I didn't enjoy this project as much as I have other projects.
