Frequency distribution is defined as a plot of the number of scores occurring for each score value or for two (2) or more limited ranges of score values . It is an organized display of a set of scores that shows how many scores are located in each category on the scale of measurement ; the systematic arrangement of scores on a measure to reflect how frequently each value on the measure occurred. Moreover, Frequency distribution is defined as a description of the number of times the various attributes of a variable are observed in a sample. The report that 60 percent of a sample were married and 40 percent were single, is a simple example of a Frequency distribution.
