Try a simple, straightforward answer.
Try providing a "placebo" answer for your research questions.
This will help you understand if your questions are clearly
formulated or not.
E.g. could "yes" be an answer to the question? If so, make sure
to explain why you are writing more than just "yes" or
"no".
Try answering without context.
Imagine how to answer the question without thinking of
your approach. What would be a logical way to work to
address this question?
If this does not result in your desired approach, update
the question and/or your approach.
Figures and tables
Charts/functions: Label the axes clearly.
Is it clear what the table/figure shows?
Is it clear what you want to show by including this
table/figure?
Credit sources - even if a source is only partially
responsible for the information in the figure/table:
credit them.
References
Use an appropriate and uniform style (BibTex, APA, ...)
Embed the references logically.
E.g., "as Researcher et al. showed [1], ...".
References must be embedded in the report, not just
supplied as a list at the end.
Formulas
Is the idea behind the formula clearly introduced in the
text?
Is the formula necessary, or does the text suffice?
Is the formula syntactically and mathematically
correct?
E.g., no free variables, give the formula a name, a
definition is of the form "term(variables) = ...." and
not of the form "...", etc.
Can the formula be simplified (mathematically,
logically)?
If so, then use a simplified version.
If the simplified version is too simple, then
the idea behind the formula may be erroneous.
