Lacking good statistical thinking often leads to many problems in an organization. It’s hard to define the exact scope of a given problem in many cases without having access to statistical data about that problem, and as a result, if the problem statement is not clear, identifying the root ...
and “What is a parameter?” The notions that a model must “makesense,and that a parameter must “have a well-defined meaning’ are deeplyingrained in applied statistical work, reasonably well understood at aninstinctive level, but absent from most formal theories of modelling andinference. In...
Statistical significance is a determination made by an analyst that the results in data aren't explainable by chance alone. Statisticalhypothesis testingis the method by which the analyst makes this determination. The test provides ap-value, which is the probability of observing results as extreme a...
