Answer:
scientific method
Explanation:
The primary aim of research and scientific experiments conducted by scientists is to solve problems and provide factual answers to them. In order to accomplish this, a procedure called scientific method is employed.
Scientific method refers to a step-by-step procedure used to test the validity of an hypothesis. Scientific method uses the following steps;
1) Make observation
2) Ask a question
3) form an hypotheses.
4) perform an experiment
5) Analyze the results
Hence, SCIENTIFIC METHOD describes a series of steps designed to answer questions.
