Frequency Distribution of Ungrouped Data

The frequency is the number of times the value occurs in the data set. A frequency distribution is an organization of raw data in tabular form, using classes (or intervals) and frequencies.

The total of the frequencies in the distribution is symbolized by the letter N. The frequency distribution might show a pattern in the set that is not apparent when simply examining the individual values.

The types of frequency distributions that will be considered in this section are categorical, ungrouped, and grouped frequency distributions.
