At the beginning of this project, my group gathered data on how different people walked, using an accelerometer app for our phones. We put all the data into a spreadsheet, for easier visualization. Then, we compared different attributes of the gaits we recorded with other factors like height and weight, to try and find a relationship. Once we found something, we created a research paper detailing our results, which can be found below. We also gave a small presentation to the rest of our class on the results, which can also be located below.
Concepts Used:
Frequency: Frequency is the number of times something happens per second. It can be calculated using the formula F=1/T, where F is the frequency and T is the time it took. In this project, we used frequency to determine the number of steps per second the subjects took, so we could attempt to relate that number to other characteristics. Frequency can be measured in Hertz (Hz), which means "cycles per second".
Predictive Model: A predictive model is an equation created to attempt to determine a pattern in data. It represents a trend that you think exists in the information, and extends said trend to allow you to make educated guesses about other points in your data-set. The equation we created was a predictive model, because it took the data we had, noted that the average ratio of height to gait frequency was 3.32, and created an equation to predict other people's heights based off their gait frequency, extrapolating off the data we had.

Reflections:
There are a few things I did well in this unit. One was self-sufficiency. For a large amount of the work time in class, the rest of my group was working on another project, and I was the only one doing gait analysis. Regardless, I worked well, and didn't need to request help much. Another item I succeeded at was the analysis portion. I recognized that our methods were somewhat flawed, and noted that, preventing us from thinking we were finished before we actually were.
I had some failures in this unit, though. For one, I didn't communicate well with my team. Though I have moved past the point were I struggled to talk when my team was sitting next to me, I still struggled when I couldn't just walk up to my group members and talk to them, because they were busy most of the time. I also wasn't very good at understanding the tasks set before me. For the first part of this unit, I was utterly confused as to what out end product was going to be. I figured it out, but I was perplexed for a while. In the future, I will have to realize sooner.
