Cumulative Relative Frequency Distribution:
A cumulative relative frequency distribution is a tabular summary of a set of data showing the relative frequency of items less than or equal to the upper class class limit of each class. Relative frequency is the fraction or proportion of the total number of items.
This definition holds for quantitative data and for categorical (qualitative) data (but only if the latter are ordinal – that is, a natural order of items is specified).
