distribución

A classification of events according to location along a continuum. For example, an IRT distribution classifies IRTs into several temporal categories (e.g., less than 1 second, I but less than 2 seconds, 2 but less than 3 seconds, and 3 or more seconds). Frequency distributions show the number of events per category; relative frequency distributions show the events per category as a proportion of the total. Each category is called a class interval, and class intervals are ordinarily of equal size. Distributions often include a category for all events failing beyond some point on the continuum (e.g., in the above example, 3 or more seconds) so that a category exists for any event no matter how extreme its value.
