Q. What do you mean by Scientific Methods?
A scientific method is a systematic approach utilized to answer a question or study a situation. It is both an organized manner for scientists to do research and a way for scientists to verify the work of other scientists. A usual scientific method includes forming a hypothesis, performing an experiment, making observations and arriving at a conclusion.
Scientific study typically begins with observations. Frequently a scientist will begin with qualitative data-information that describes odour, shape, colour or some other physical characteristic that relates to the five senses. Chemists as well use quantitative data. This kind of data is numerical. It tells how little, how much, how big or how fast.
