Science Buddies: "Ask an Expert"

I am doing my science fair experiment on Emmert's law and the full moon illusion, after doing one part of my experiment with 50 participants, I have run into graphing issues. I have to compare the distance away from the screen to the diameter of some circles. I have 5 different circles and a distance for each circle for all 50 participants. I'm working on Excel and prefer to use a bar graph. Any help is appreciated with what graph and how to graph it. Thanks

Hi abby816,

I'm not sure if I understand what exactly you're asking for. What are you having issues with?
Please read point 12 of part 1 for directions on graphing: https://www.sciencebuddies.org/science- ... #procedure
