Welcome
What are you trying to do?
Two questions, then a plan for your particular work rather than a tour of the software.
A thesis or dissertation
You are collecting your own data and writing it up for an examiner.
A study for my organisation
A survey, evaluation or assessment that has to stand up to a funder, a board or a regulator.
Data I already have
A file from somewhere else that needs analysing properly.
Something I need to watch regularly
The same question every month, where the answer only means something beside last month.
