Data Collection
Did the researchers use more than one way to observe the same phenomenon?
Was there evidence of validity by triangulation?
Was there any quantitative data? Frequency counts are common.
Notes:
Several methods of data collection is desirable.
Triangulation means you’ve looked at things from more than one angle:
Multiple instruments - field notes, interviews, documents
Multiple observers or researchers evaluate the data, independently
Have reached consensus about what was present
Some quantitative data may be present.
Quotes and anecdotes should be available to the reader.
So should surveys and the cover letter that goes with the survey.
