Frequency Distribution Mastery: Part- 1 (Khóa học)

How to form a frequency distribution table where the data in respect of blood groups of many students is given and how we can say which is the most common and which is the rarest blood group among the students.

How to construct a grouped frequency distribution table when the data in respect of few engineers is given who reside at different distances from the place of work.

If the data in respect of humidity of a certain city for a few days is given, how to construct a grouped frequency distribution table when class size is also given. And how to find the range of the data?

How to form a grouped frequency distribution table when the data in respect of height of many students is given along with class intervals and what conclusion we draw from the table about the heights of students.

When the large amount of data is to be presented, we can condense the data in to groups and these groupings are called “classes” or “class-intervals” and their size is called the class-size or class width. In each of these groupings/classes, the least number is called the lower class limit and the greater number is called the upper class limit.
