Answer: A hypothesis instead of a guiding question is most likely used in a Scientific experiment.
When conducting a scientific experiment, the researcher aims to either prove or disprove a hypothesis by collecting data through experiments. A hypothesis is a tentative statement that explains the relationship between two or more variables and should be testable, falsifiable, and specific. The data obtained from the experiment should support or refute the hypothesis.
On the other hand, case studies, observations, and surveys involve collecting data by observing or interviewing people or studying a particular situation. While these methods may use guiding questions to aid in research, they do not necessarily involve a hypothesis that can be proven or disproven through experimentation.
