Final answer:
The experimental method is preferred because it allows for the manipulation of variables in order to establish cause-and-effect relationships and test hypotheses.
Step-by-step explanation:
The experimental method is a preferred means of gathering information because it allows for the manipulation of variables. In an experiment, researchers can control specific variables and observe how changes in those variables affect the outcome. This allows them to establish cause-and-effect relationships and test hypotheses.
For example, if a scientist wants to study the effect of temperature on the growth of plants, they can set up an experiment with two groups of plants. One group is exposed to high temperatures, while the other is kept at a normal temperature. By comparing the growth of the two groups, the scientist can determine whether temperature has a direct impact on plant growth.
By manipulating variables and conducting controlled experiments, scientists can gather reliable and accurate data to support their hypotheses and theories.
