What are your thoughts? There are a couple obvious sources of error, but you need to go first. Are you familiar with the mathematical analysis of diffraction grating patterns?

Also, is this a schoolwork question?

Yes, I am familiar with diffraction patterns and its theory.
No, this is not a school work question, it is a personal question, otherwise I would have sent the question in the relevant section.

Great. So what do you think the top couple sources of error would be, and how would that affect the output data?

I think an error could be to read the diffraction angle. Because people may read different angles, albeit with slight differences. And because the diffraction angle is related to the wavelength, can affect it.

I, for one, am waiting for your best effort to catalog all the errors. This avoids us telling you things you already know and allows us to understand at what depth to proceed.

Sounds a lot like "Hop to it! It's due Friday!"

Add me to the list of people waiting for your best effort. If it helps, many people are willing to put as much effort as you are. But not much more.
