Scientific research is most clearly expressed in the experiment, which investigates cause-and-effect relationships between two(or more) variables under controlled laboratory conditions.
Step-by-step explanation:
- An experiment includes different steps where research people will investigate the cause-and-effect by showing the outcomes which came when the particular factor got manipulate.
- The function of an experiment is to validate the hypothesis. A hypothesis is an explanation which lacks established theory. A hypothesis is testing through research study and experiment.
- An experiment can vary according to its scale and goal but it always relies on the logical analysis and of the results and repeatable trials.
