Is a summary display for (1) the frequency of each individual score or category (ungrouped data) in a distribution or (2) the frequency of scores falling within defined groups or intervals (grouped data) in a distribution. Are a set of scores distributed into intervals, where the frequency of each score can fall into any given interval. For data that covers a wide range of values. Steps needed to construct a simple frequency distribution for a grouped data. 9 would be the real range of the data.
