Final answer:
The disadvantage of qualitative research is its lack of generalizability and difficulty in organizing and interpreting varied data sets, as the methods used are highly contextual and influenced by personal interpretation.
Step-by-step explanation:
The main disadvantage of qualitative research is the lack of generalizability. This is due in part to the typically small, non-random sample sizes used in qualitative studies, such as case studies, and the subjective nature of the data collected. Qualitative data are deeply contextual and, because they are often collected through methods like interviews, participant observation, and case studies, the findings may not be applicable to a larger population. Participant observation, likely used by a symbolic interactionist, generates rich, in-depth data, which offer valuable insights but can also reflect the biases of the researcher and the respondents. The inherent subjectivity and variability of qualitative data make it difficult to replicate studies and apply the findings broadly. Furthermore, it's challenging to quantify phenomena from qualitative data, as it's more about understanding the depth and complexity of human behavior than measuring it.
Surveys can offer both quantitative and qualitative data, but when they include open-ended questions, the responses become qualitative in nature, reflecting personal opinions and beliefs. These responses require interpretive skills from researchers and provide a wide range of non-standardized data. While the depth of information from such qualitative responses can be illuminating, organizing and analyzing this varied data set can be cumbersome and complex.
