Cumulative Frequency is The total of a frequency and all frequencies so far in a frequency distribution. It is the 'running total' of frequencies in the frequency distribution table.
The frequency distribution table lists all the possible events and how many times (frequency) they occurred.
In a frequency distribution table, there are usually five parts/columns (12th grade statistics):class, frequency, mid-point, relative frequency, and cumulative frequency.

A frequency distribution of numerical data where the raw data is not grouped.
Frequency distribution refers to a set of frequencies with a particular set of values into which a statistical population is grouped. Relative frequency refers to data presented in a table that demonstrates the relative frequency of multiple non-overlapping classes.
Because in case grouped frequency distribution table we are sending all i.e mixed frequencies at a time with diff bandwidth wheras in case of regular table we are sending each signal at a time.
Yes.
A frequency distribution can be best interpreted if it is transformed into a frequency table with the tabulated data obtained from data gatherings such as but not limited to: poll, survey, grade, questionnaire, demographic, monthly/semestral/annual report.
A histogram is used when data is condensed into a frequency table. It displays the frequency of data within fixed intervals or bins, providing a visual representation of the distribution of the data.
