While including a data table for a lab report, the guidelines asked to include an uncertainty value for each raw data. In this particular lab where we used slotted masses the masses were already given (such as 50g, 200g, etc.). So while recording the masses into the data table, to how many significant figures should I record the uncertainty and for what reason?

I understand that it is the mathematical function needed to interpret the data, but this makes no sense to me mathematically.

Why must an electric field (as a function of time) be Fourier transformed to offer meaningful spectroscopic information? In other words:

Why doesn't a computer simply interpret the raw data, how does the Fourier transformation mathematically make the data easier to interpret?

In various applications where we are dealing with electromagnetic or acoustic waves, such as medical imaging, we use the space ${L}^{2}$ or the related Sobolev space ${W}^{1,2}$. I have never seen a reason given for this. Does anyone know why these spaces are preferred over say ${L}^{1}$ spaces?

Raw data is data that has not been processed. It can be collected from surveys, observations, or experiments. Raw data examples can include measurements, notes, and transcripts. Raw data problems can occur when data is not properly collected or when it is not properly processed.
