Or you could use a drop-box or other more sophisticated system.
The origin and intercepts are often important so, unless the ranges of your data make it impractical, the zeros of one or both scales should usually appear on the graph.
Then put all the folders in a box or a filing cabinet.
There is a good chance that this test will be applied: sometime after you have left, another researcher will want to do a similar experiment either with your gear, or on a new set-up in a foreign country.
Do not keep back-up close to the computer in case the hypothetical thief who fancies your computer decides that s/he could use some disks or membory as well.
If you have any characteristic grammatical failings, check for them.
"Objects of very different albedo may be illuminated differently soas to produce similar reflected spectra" is longer and uses less common words, but, compared to the former example, it has the advantage of being true.
How should it be written?Your thesis is a research report.
You should be careful not to use this presentation too much: your thesis must be a connected, convincing argument, not just a list of facts and observations.
The readers of a thesis do not know what the "answer" is.
Good referencing also tells the reader which parts of the thesis are descriptions of previous knowledge and which parts are your additions to that knowledge.
Obviously your examiners will read the thesis.
For example, the sentence "After considering all of these possible materials, plutonium was selected" implicitly attributes consciousness to plutonium.
More commonly theses are now stored in an entirely digital form.
Good referencing allows us to check the foundations of your additions to the structure of knowledge in the discipline, or at least to trace them back to a level which we judge to be reliable.
These may be stored as .pdf files on a server at your university.
The only arguments I have ever heard for avoiding the active voice in a thesis are (i) many theses are written in the passive voice, and (ii) some very polite people find the use of "I" immodest.
The short answer is: rather more than for a scientific paper.
The only exceptions are cases where every researcher in the field already knows it: dynamics equations need not be followed by a citation of Newton, circuit analysis does not need a reference to Kirchoff.
