In statistics the class boundaries are numbers that separate classes without forming gaps. To find the lower, you subtract 0.5 and to find the upper, you add 0.5. If the class is 3-7 the lower class boundary would be 2.5 and the upper 7.5. The upper boundary of one class will equal the lower boundary of the next class.

What is class boundary in statistics?
class boundary is the midpoint between the upper class limit of a class and the lower limit class of the next class sequence when making a class interval starting at the lowest lower limit in the bottom of a table.
What is class limit according to statistics?
The lower and upper limits of a class interval are known as Class Limits.
What is class size in statistics?
The difference between the upper and the lower limit and we must add + 01 for that difference ..that is called a class size or widthex:-lower class limit = 10upper class limit = 20(20-10) + 1 = 11the answer is = 11
How do you get the class interval for ungrouped data in statistics?
same as grouped data i.e. (upper limit+lower limit)/2
What is sigma in statistics?
Since this is regarding statistics I assume you mean lower case sigma (σ) which, in statistics, is the symbol used for standard deviation, and σ2 is known as the variance.
