Webban normally distributed empirical distribution can be made to correspond to the theoretical distribution by using z scores; using z scores calculated from the raw scores of an empirical distribution, you can determine the probabilities of empirical events, i.e., IQ scores, tree diameters, hourly wages, or any empirical event that are distributed normally WebbProbability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.
