. Reporting
(a) ‘think aloud’ reporting, immediate retrospective reporting after a task, open interviews, or diary type of reports
heavy on Data Analysis transcribing them (if spoken) and categorising what people say, and often contain material suitable for purely qualitative analysis
(b) structured interviews, closed questionnaires or attitude rating inventories and judgment tests
more work in constructing the Materials beforehand, and the Data Analysis may be fairly automatic (and computerisable).
