Compare qualitative data collection methods (interviews, focus groups, observations) in terms of data richness and potential biases.

• A. Interviews are deep but time-consuming; focus groups are interactive but may be dominated; observations capture context but can be observer-influenced.
• B. Interviews are fastest; focus groups are impersonal; observations always require a large sample.
• C. All methods produce identical data richness.
• D. Focus groups are never biased.

Answer: (A)

Qualitative data collection methods differ in how rich the data can be and in the biases they introduce. Interviews yield deep, detailed, individual insights because you can probe experiences and perceptions in depth, but they take substantial time to conduct and analyze. Focus groups provide rich data through dynamic interaction, revealing how ideas emerge and how participants influence each other, yet group dynamics can cause voices to dominate or participants to conform, biasing what’s captured. Observations offer contextual, in-situ information about behaviors and settings, giving a strong sense of real-world action, but the presence of an observer and the observer’s interpretations can bias what is noticed and recorded.
