Answer 2

Q. The cumulative frequency of a class is the frequency obtained by adding the frequency of all up to the classes preceding the given class.

what does it mean?​

Answer:  Cumulative frequency is the collection of all previous frequencies together.

Step-by-step explanation: To find the cumulative frequency for a class, take the number in the current class and add on the previous cumulative frequency for the class below, for example, for 1900–2000 we have a frequency of 92. The cumulative frequency for 1800–1900 is 859. Add 859 + 92 to get the cumulative frequency of 951
