Cumulative frequencies in a grouped frequency table are useful to find . . .

A. Mean

B. Median

C. Mode

D. All of these

Answer :

The cumulative frequency of a set of data or class intervals of a frequency table is the sum of the frequencies of the data up to a required level. It can be used to determine the number of items that have values below a particular level.

**Mean** is simple or arithmetic average of a range of values or quantities, computed by dividing the total of all values by the number of values. And The **mode** of a set of data values is the value that appears most often.

While, **median** is the middle value of the set of ordered data. The position of the median is given by {(n + 1)/2}^{th} value, where n is the number of values in a set of data.

So, the formula can be applied in the cumulative frequency in an arranged data to find the median.

Thus, (B) is the correct option.
