Final answer:
Field research data may be influenced by the researcher's presence and perspective.
Step-by-step explanation:
Field research data may be influenced by the researcher's presence and perspective. Field research is a method of gathering data by observing and interacting with people in their natural environment. However, the presence and perspective of the researcher can introduce bias into the data collected. For example, the researcher's personal beliefs, attitudes, and expectations can influence how they interpret and record the observations. Therefore, it is important for researchers to be aware of their own biases and strive for objectivity when conducting field research.
