Class boundaries are defined as the average of the upper limit of one class and the lower limit of the next class.
For example:
No. of runs (class)
0-4
5-10
10-15
15-20
and No. of batters (frequency)
3
9
10
4
So the upper class boundary for the first class is the average of 4 (upper limit of class 0-4) and 5 (lower limit of next class 5-10), i.e. 4.5.
Similarly, the next boundaries are 10.5, 15.5 and 20.5.
In this way, there's no gap between 2 bars of a histogram, i.e., in this example the bars range from:
0-4.5
4.5-10.5
10.5-15.5
15.5-20.5
(Hope this helps! Took me a while to understand this stuff too :D)

How do you calculate the class boundary of the first class in statistics?
To calculate the class boundary of the first class in statistics, subtract 0.5 from the lower class limit of the first class and add 0.5 to the upper class limit of the first class. This is done to account for the fact that class boundaries fall halfway between the class limits.
What is the upperclass boundary of the class 23-35?
The upper class boundary of the class 23-35 is 35. In a class interval, the upper class boundary is the highest value that can be included in that class. Therefore, for the class 23-35, the upper boundary is 35, which signifies the maximum value within that range.
What is the upper class boundary of the class 23-35?
The upper class boundary of the class 23-35 is 35. In class intervals, the upper boundary is typically the highest value of that range, which in this case is the upper limit of the interval.
What is the meaning of lower class boundary in statistics?
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.
How do you get class boundary from given class marks?
To find the class boundaries from given class marks, you need to identify the upper limit of one class and the lower limit of the next class. The class boundary is typically calculated by taking the average of these two values. For example, if the class marks are 10-20, the class boundary between these classes would be 20 (upper limit of the first class) and 10 (lower limit of the next class), resulting in a boundary at 20.5. Repeat this process for each pair of consecutive class marks to determine all class boundaries.
How do you work out the class boundaries?
To calculate class boundaries, add 0.5 to the lower class limit and subtract 0.5 from the upper class limit of each class interval in a frequency distribution. This creates a buffer zone between the classes to avoid overlap when graphing or analyzing data.
What are the components used in the frequency distribution?
class limit. class boundary. class mark. class widh.
What is 48.6 class boundaries and class limits?
class boundary is 48.6 class limit is either 48.1 or 49.1
What is 4.4 class boundaries and class limits?
class boundary is 4.4 class limit is either 3.9 or 4.9
What is the class boundary for 7 feet?
6.5 and 7.5
How do you get the lower class boundary of the median?
The median is the middle number in a data set. The lower class boundary is the first quartile or number that is 25 percent lowest in the data set.
