by counting them
class frequency is the number of observations corresponding to a particular class.
Class Frequency
How can a class frequency be equal to zero?
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
To calculate the frequency density we will simply divide the frequency by the class width.

No.
Cumulative frequency is the running total of class frequencies.
Frequency Density multiplied by the class width
