The scientific method begins with the observation of phenomena or natural events. Scientists use inductive reasoning to combine isolated facts into model plausible explanation, or hypothesis.
Scientists use deductive reasoning to design an experiment to test their hypothesis. Scientists develop a good experimental design that contains both a(n) experimental group in which the experimental variable is altered, and control group in which the experimental variable is not altered. The results of an experiment are called data e and must be analyzed in order for a conclusion to be reached.
