Answer:
scientific
Explanation:
A scientific method can be defined as a research method that typically involves the use of experimental and mathematical techniques which comprises of a series of steps such as systematic observation, measurement, and analysis to formulate, test and modify a hypothesis.
A hypothesis is considered to be tentative or an educated guess and can be defined as a testable explanation for an observation or a scientific problem. An example of a hypothesis is saying, Corona virus is caused by the introduction of the "5G" technology.
Thus, for any hypothesis to be true and acceptable in science, it must be supported by observations and the results of control experiments; this give rise to factual informations, theories and by extension solutions to problems. Consequently, we can deduce from the aforementioned paragraphs that a scientific method is simply an organized way to test scientific ideas and hypothesis.
Basically, the goals of science include the following;
I. Measurement and description of events or subjects that are being studied through research and experimentation.
II. Understanding and prediction of the natural and physical world by understanding the reason for each occurrence.
III. Application of scientific laws and control of mechanisms to proffer solutions to practical or real-life problems.
<em>In conclusion, the scientific approach assumes that events are governed by some lawful order by uncovering all of the laws or consistencies associated with them.</em>
