I would think before answering, revise any specific terminology for that topic and also look at words such as "reliability, accuracy, precision, validity" etc and ensure that you know what they mean. Hope this helps!
for example i am talking about using an optics bench instead of a ruler for the diffraction grating experiment. I have to comment on why i have chosen the optics bench and ruler. but I'm getting accuracy, validity, precision and reliability.
i know I'm talking about physics atm but i have no idea who to go to!!!
