Elements of Statistical Methods Probability (Ch 3) - Statistics

Frequentist Interpretation of ProbabilityIn common language usage probability can take on several different meanings.E.g., there is the possibility, not necessarily certainty.There is a 40% chance that it will rain tomorrow.Given the current atmospheric conditions, under similar conditions in the pastit has rained the next day in about 40% of the cases.or: about 40% of the rain gauges in the forcast area showed rain.Both of these are examples of the frequentists’ notion of probability,in the long run what proportion of instances will give the target result?The 40% area forecast may need some thinking in that regard to make it fit.1
