摘要：

Scientific Inference is a process of drawing conclusions from systematic observations aimed at explaining phenomena.Scientific reasoning depends on making generalizations, or inductions, from observations to general laws of nature.The process of formulation scientific hypotheses involves induction from systematic observation.Inferences of cause-effect relations are required to solve public health problems demanding action. A single epidemiologic study that investigates a causal hypothesis constitutes a single test of that hypothesis,and the closer the study comes to approximating the causal contrast, the greater the rigor of the test, and the greater the strength of the resulting evidence for or against causation,with strong evidence, the generally resulting from multiple rigorous tests, is required to infer causation.
