Answer:
A researcher interested in making a causal claim may choose not to conduct an experiment for several reasons. Firstly, experiments can be costly and time-consuming, requiring substantial resources, including funding, equipment, and participants. Depending on the scope and complexity of the research question, an experiment may not be feasible within the available constraints. Secondly, experiments often involve manipulating variables and controlling conditions, which may not be ethically or practically possible in certain situations. For example, studying the long-term effects of a particular event or historical phenomenon may be impossible to replicate in a controlled experimental setting. Additionally, there may be practical limitations to conducting experiments in certain fields where the variables of interest cannot be directly manipulated. In such cases, researchers may rely on observational studies or other non-experimental methods to examine causal relationships based on existing data or natural variations in the real world.
