Final answer:
Unstructured observation is not used for studies in which hypotheses are to be tested.
Step-by-step explanation:
In the context of scientific studies, unstructured observation is not used for studies in which hypotheses are to be tested. Therefore, the statement is false.
Observation is the act of gathering information or data through the senses, such as seeing, hearing, or smelling. It involves simply observing and describing what is happening or what is being observed.
Hypotheses, on the other hand, are testable explanations or predictions based on existing knowledge or observations. They are formulated to guide scientific investigations and experiments.
