摘要:Too few researchers understand what statistical significance testing does and doesn't do, and consequently their results are misinterpreted. Even more commonly, researchers understand elements of statistical significance testing, but the concept is not integrated into their research. For example, the influence of sample size on statistical significance may be acknowledged by a researcher, but this insight is not conveyed when interpreting results in a study with several thousand subjects. This article will help you better understand the concept of significance testing. The meaning of probabilities, the concept of statistical significance, arguments against significance testing, misinterpretation, and alternatives are discussed.
