... In this scenario we use a random sample of a categorical variable to learn about the proportion in the population that have a specific value (generically called success) for this categorical variable. Data: A single categorical variable. Example: Estimate what proportion of Grand Rapids residents wi ...

The criticism that single-locus interpretations are not testable hypotheses is true but increasingly irrelevant as the entire field ...

Probabilistic reasoning and statistical inference
... Another problem is that the interpretation of probability as relative frequency can’t make intuitive sense of the fact that probabilities can attach to non-repeatable events, e.g. the probability that the next flip of this fair coin will be heads or the probability that the Heat will win the 2012 NB ...
