A1, 2 and 3 only

C3, 4 and 5 only

D2, 4 and 5 only

Correct answer: (B) 2, 3 and 4 only

Explanation

The similarities are answering research questions, relating data analysis to literature, and being concerned with variation.

Both traditions set out to answer clearly framed research questions.

Both connect their data analysis back to existing theory and literature.

Both are concerned with variation and with explaining differences in their cases.

Data increase is wrong, since quantitative work rather reduces data into summary form.

Use of null hypotheses belongs to quantitative testing alone, not to qualitative research.
