I need help on my science fair project.
I found the project on the site Science Buddies it's called Leaves and Light. I know what to do and I am finished with the experiment itself but I need help with analyzing the data. The data table given on the website is not very specific in that it uses no numbers but colors instead. I can easily fill in the table but when it comes to graphing the data a problem occurs. I don't know how to graph the data without using numbers. I mean I'm not sure that my teacher would find accuracy based on just my judgement(not that my judgement is impared). So Basically I need to know can you accurately make a graph without using numbers based on your own judgement. Thanks in advance.
Here is the site to find the project:
