  • Frequency probability is the [probability interpretations] that defines an event's Probability as the limit of its relative frequency in a large number of trials. The frequentist account overcomes some of the problems of the previously dominant viewpoint, the [Classical definition of probability]. Frequentist statistics is often associated with the names of Jerzy Neyman and Egon Pearson who described the logic of statistical hypothesis testing. Other influential figures of the frequentist school include John Venn and Richard von Mises.
  • Frequentists talk about probabilities only when dealing with well-defined Random Experiments. The set of all possible outcomes of a random experiment is called the Sample Space of the experiment. An event is defined as a particular Subset of the sample space that you want to consider. For any event only one of two possibilities can happen; it occurs or it does not occur. The relative frequency of occurrence of an event, in a number of repetitions of the experiment, is a measure of the probability of that event.
