Web-Frequency distributions for quantitative data are just like those for qualitative data, except that the data are divided into classes rather than categories-The classes are intervals of equal width that cover all the values that are observed.-For example, we could choose the classes to be 0.00-0.99, 1.00-1.99, and so forth. Probability distribution fitting or simply distribution fitting is the fitting of a probability distribution to a series of data concerning the repeated measurement of a variable phenomenon. The aim of distribution fitting is to predict the probability or to forecast the frequency of occurrence of the magnitude of the phenomenon in a certain interval.

1.3 Frequency, Frequency Tables, and Levels of Measurement

The cumulative frequency is the total of the absolute frequencies of all events at or below a certain point in an ordered list of events. The relative frequency (or empirical probability) of an event is the absolute frequency normalized by the total number of events: The values of for all events can be plotted to produce a frequency distribution.
