Question

In the chapter statistics of class 9, in the topic
Constructing Histogram for Data Having Different Class
IntervalsThere is a video which tells us that the formula for
calculating adjusted frequency is "minimum class size/ class size X
frequency "In the next topic which isExamples on Constructing
Histogram for Non-Uniform Class SizesThere is a video which tells
us that the formula for calculating adjusted frequency is"
frequency of class interval/ class size of that class X minimum
class size"So, which one is the correct method or the conventional
method?
