Answer 2

Answer:

cumulative frequency is nothing but u need to add the frequencies either from top to bottom or vise versa

Step-by-step explanation:

as in the above problem in

frequency column u can see the nos starting from 5 and next no is 8

so in the first row keep the no as it is I.e 5

next add 5+8=13

next add 13+11=24 and so on here the answer what u get should be added to the next frequency mentioned.

the cumulative frequency final number should be equal to n otherwise it means that you have gone wrong somewhere...
