Using data to find a quadratic graph of best fit is an awesome way to connect math with the real world. However, it’s not always easy to find authentic data to use for a quadratic regression equation. I REALLY wanted to use the flight of a soccer ball or golf ball and find a video on YouTube that had all the stats using a trace finder that states the distance and height. I searched and searched, but could not find a video that was clear and had the information needed to collect data for a scatter plot. So, I began looking at weather patterns, but that wasn’t quite right either. However, it helped me stumble across the timeanddate.com site. This is when I realized I can use the time of day and the altitude of the sun for a quadratic regression real world project! Of course, you can only use it for ONE day otherwise, it’s a periodic function. Here are the details of the project...
OBJECTIVE
In this project, students are to find the curve of best fit for a quadratic function in the real world by performing the following:
VISUALS The Google Slides template is provided, so students can type in their information in the specific location. They then can easily turn their project into you via Google Classroom or email.
The project directions and rubric are 100% editable! This is very easy to integrate into any Algebra course either inperson or online, gives students some freedom of what place to research, and is mathtastically fun! And since it’s editable, you can even change it to record data over several days and find the sinusoidal regression equation for a higherlevel math course.
