2. INTRODUCTION
In research methodology,non-
response refers to the failure of
selected participants to participate in
a study.Understanding non-response
is crucial for ensuring the validity and
reliability of research findings. This
presentation will explore the causes,
impact,and strategies for addressing
non-response in research.
3. Causes of Non-Response
Non-response can be caused by
various factors including lack of
interest, time constraints, and
sensitivity of the topic. Other
reasons may include distrust of
researchers, language barriers, and
technical issues.Understanding
these causes is essential for
mitigating non-response bias.
4. IMPACT ON RESEARCH
VALIDITY
Non-response can lead to bias and
underrepresentation of certain
groups in the sample.This can
affect the generalizability and
accuracy of research findings.It is
important to assess the extent of
non-response and its potential
impact on the study results.
5. STRATEGIES TO ADDRESS
NON-RESPONSE
To mitigate non-response,
researchers can use
incentives, multiple contact
attempts, and personalized
communication.Utilizing
mixed-mode surveys and
employing non-response
weighting techniques can also
help improve response rates.
6. Non-response in research methodology poses
significant challenges, but proactive measures can
help minimize its impact. By understanding the
causes, addressing ethical considerations, and
implementing effective strategies, researchers can
enhance the quality and credibility of their studies.
