Hi there,
What was the experimental design of your UV experiment? What did you measure? Were all the plants treated the same other than distance? Did you measure how long it took for the plants to die? Did you have more than one plant at the same distance (number of samples per condition)?
As I understand it, you placed duckweed plants at varying distances away from a light source and looked to see which plants were happiest?
Depending on what your measurement was, you could do statistical analysis and plot those results in a graph or table.
For example, if all the plants were treated the same except for distance from light, and you looked to see if they were alive at one time-point, you could plot distance away from light versus plant height (which can be an indicator of how healthy a plant is) in a line graph.
You could also display your results in a table indicating distance away from light and alive (+) vs. dead (-).
Here's a link to help with statistical analysis definitions and calculations:

Here's a helpful link from the Science Buddies "How to do an experiment" toolkit for "Data Analysis and Graph":

Depending on what your hypothesis was, you would want to gear your analysis and how you show your data to demonstrate whether your experiment as proven or disproven your hypothesis.
Hope this helps and good luck!
