Some of these points even represent incorrect norms for rational thinking. The use of appropriate norms and the admission of null intervals could remove some of the distortions inherent in this paradigm. Sriram's suggestions of how to test streakiness in tennis games illustrates the flexibility of this approach. The distinction between descriptive and inferential statistics is indeed arbitrary. Inferential statistics produce decisions concerning the status of hypotheses that can only be made if a decision criterion is agreed upon.
Descriptive statistics depend wholly on the data sampled.
Researchers only decide which statistics to compute, but not what to infer from them. He notes that this is done routinely in neuro-imaging studies because it facilitates communication among researchers. He also notes that the ambiguities of p are well-known, which I take to mean that people realise that p is a confounded index. In a simulation study, Greenwald et al. This finding is provocative and important, but the method requires a crucial modification.
