Question

i am trying to figure out how to find class boundaries

Answer 1

When we have different classes of data, there is always an upper and lower class limit for it. i.e, the dataset has the smallest and largest value. Class Boundary is the mid point of the upper class limit of one class and the lower class limit of the subsequent class.  

Class Boundaries are found by adding 0.5 to upper limits and by subtracting 0.5 to lower limits for whole number data. If the data has one decimal place we will use 0.05 and so on.

This is how, you can find the class boundary.
