Assertion (A) : The 'diary' technique enables to collect data about daily activities and experiences of the respondents, recorded by himself.
Reason (R) : The 'diary' technique is the most used technique in Delphi research.

  • A.Both (A) and (R) are true
  • B.Both (A) and (R) are false
  • C.(A) is true but (R) is false
  • D.(A) is false but (R) is true

Answer: C

The answer is (A) is true but (R) is false.

Assertion (A) is correct: in the diary technique respondents themselves record their daily activities and experiences over a period, giving the researcher data that would be hard to observe directly, for example how often and why they use a library.

Reason (R) is false. The Delphi method gathers the opinions of a panel of experts through several rounds of questionnaires with controlled feedback, not through diaries. So the options calling (R) true are wrong.
