Which of the following reliability techniques are used in qualitative research? A. Diachronic reliability B. Quixotic reliability C. Synchronic reliability D. Holsti's constant E. Chronbach's alpha Choose the correct answer from the options given below: Correct Answer A, B and C only

The reliability of a statistical analysis conveys that a methodology being used for interpreting data is consistent and would give uniform results every time it is used.

Key Points Quixotic Reliability:

  • Quixotic reliability can be viewed as an attempt to measure how far a particular method can continuously lead to the same measurements and final results.
  • However, many researchers and authors have rejected this approach of defining reliability as misleading and trivial.

Diachronic Reliability:

  • Diachronic reliability is understood as the stability of measurements or observations in their temporal course.
  • The issue here is the precondition that the phenomenon under study in itself may not undergo any changes so that the criterion remains effective.

Synchronic Reliability:

  • Synchronic reliability is the consistency of results collected at the same moment in time but by using different instruments.
  • This criterion is most instructive when it is not fulfilled as viewed by various researchers.
  • The issue then follows as to why this is the case and also brings out questions concerning the various perspectives on the issue resulting from different methods applied by numerous researchers.

Additional Information Difference between validity and reliability.

Validity Reliability
The extent to which a test measures and what it claims to measure. Consistency of the test results.
Measures whether the extent to which the test claims to measure is achieved. Measures whether the test result gives consistent results as an outcome.

Therefore, the correct answer is A, B, and C only.
