What is a major limitation of using questionnaires in primary research?

Using questionnaires in primary research often faces the significant challenge of low response rates. This limitation arises from various factors, including participant fatigue, lack of time, or disinterest in the survey topic. When individuals do not participate or complete the questionnaire, the data collected may not accurately represent the larger population, leading to potential biases and reduced validity of the research findings.

Low response rates can also result in a smaller sample size, which may undermine the statistical power of the study, making it harder to draw meaningful conclusions. Therefore, addressing this limitation is crucial for researchers who aim to gather comprehensive and reliable data through questionnaires.
