## The Most Trusted Place for Answering Life’s Questions

It starts like this-

upper class- the riches &

the lower class – the poors.

middle class is between i.e. poor on the way to get richer and

become upper class.

Upper middle class is those who are in middle class on the way

to become upper class.

Chennai in particular Tamilnadu in general is little traditional

and low risk-taking.

So the process of going from lower class-> lower middle

class->upper middle class->upper class will take usually 3-4

generation.

so upper middle class are either little lower than upper class

or just above middle class.

How to Find Class Boundaries (With Examples) – Subtract the upper class limit for the first class from the lower class limit for the second class. The upper class limit for the first class is 60.9 and the lower class limit for the second class is 61. Thus, we get: 61 – 60.9 = 0.1. 2. Divide the result by two. Next, we divide the result by 2. So, we get 0.1/2 = 0.05. 3. Subtract the resultClass Limit Corresponding to a class interval, the class limits may be defined as the minimum value and the maximum value the class interval may contain. The minimum value is known as the lower class limit (LCL) and the maximum value is known as the upper class limit (UCL).Class Boundaries are the midpoints between the upper class limit of a class and the lower class limit of the next class in the sequence. It is 0.5 more or less of a class limit. Therefore, each class has an upper and lower class boundary. Example: Class Frequency 300 – 399 13 400 – 499 20 .

Difference between Class Limit and Class Boundary – A family earning between $32,048 and $53,413 was considered lower-middle class. For high earners, a three-person family needed an income between $106,827 and $373,894 to be considered upper-middle…Identify the lower class limits, upper class limits, class width, class midpoints, and class boundaries for the given frequency distribution.

The minimum value is known as the lower class limit (LCL) and the maximum value is known as the upper class limit (UCL).
