Answer» Meaning of Cumulative Frequency Series : Cumulative frequency series refers to a series in which the frequency classes of different classes are not given separately, but the frequency is written in a cumulative form. In such a category, both the boundaries are not provided, only the upper or lower limit is given. When cumulative frequency is given on the basis of the upper limit, the words ‘less than’ is written before each post value and if it is according to the lower limit, the words ‘more than’ is written while writing the cumulative frequency. While solving the question of cumulative frequency series, it is first converted from cumulative to the simple frequency. Example: of Cumulative Frequency Series.
