Definition of Frequency distribution:
As a statistical tool, a frequency distribution provides a visual representation for the distribution of observations within a particular test. Analysts often use frequency distribution to visualize or illustrate the data collected in a sample. For example, the height of children can be split into several different categories or ranges. In measuring the height of 50 children, some are tall and some are short, but there is a high probability of a higher frequency or concentration in the middle range. The most important factors for gathering data are that the intervals used must not overlap and must contain all of the possible observations.
A frequency distribution is a representation, either in a graphical or tabular format, that displays the number of observations within a given interval. The interval size depends on the data being analyzed and the goals of the analyst. The intervals must be mutually exclusive and exhaustive. Frequency distributions are typically used within a statistical context. Generally, frequency distribution can be associated with the charting of a normal distribution.
A mathematical function showing the number of instances in which a variable takes each of its possible values.
Number of times a given quantity (or group of quantities) occurs in a set of data. For example, the frequency distribution of income in a population would show how many individuals (or households) have the income of a certain level (say, $5,000 a month). It is plotted either as a step-column chart (histogram) or as a line-chart (histograph). See also distribution.
