The term statistics include various terms, including the mean, median, and mode. The mean is the summation of all the nth terms, and the median is the middle value of all the selected terms. And mode is a term that occurs most of the time in the given series.
We have to take the cumulative frequency to get the solution to some terms.
The term cumulative frequency refers to the sum of all the frequencies in a given sequence.
The term frequency refers to the times when observation will get set up.
All the set data is present in the set form concerning the gap of the same intervals. The class width is known as the difference between the upper-class limit and the lower class limit.
Class width = upper limit - lower limit
