Question

There are four forms of triangulation, namely data triangulation, ______________________, theory triangulation and ______________________.

• A. Field triangulation, methodological triangulation
• B. Investigator triangulation, methodological triangulation
• C. Investigator triangulation, interviewee triangulation
• D. Investigator triangulation, epistemological triangulation

Hint:

Mnemonic: \textbf{D-I-T-M} — Data, Investigator, Theory, Method. If an option lists these four, it’s the one.

Answer 1

The Correct Option is B

Step 1: Recall Denzin’s classic four.
Denzin (1978) outlined four widely cited kinds of triangulation in the social sciences:
1) {Data} triangulation,
2) {Investigator} triangulation (multiple researchers),
3) {Theory} triangulation (multiple theoretical lenses), and
4) {Methodological} triangulation (multiple methods).
Step 2: Fill the blanks.
Hence the blanks must be {investigator} and {methodological}. $\Rightarrow$ Option (B).
