Experimental Design and Hypothesis Testing Research is a lot like good cooking, it requires a mixture of creativity, technical skill, intuition and perseverance. Maybe this is why many scientists are also good cooks. However, scientific research differs from cooking or art or computer repair in the way it poses a question. Scientific questions must be developed in a way that makes them testable by experimentation. It is very easy to forget this simple statement.
Research requires that something is known about the system.
If studying mating behavior, at least one needs to know how to tell males from females. All of these need to be carefully investigated before the actual experiment is designed. Need a working hypothesis. Hypothesis is a tentative proposition that subject to verification through investigation. It must be possible that the test results do not support the hypothesis.
