Let's say you're measuring a continuous variable such as height or speed. You collect tally charts with classes 30 - 39, 40 - 49, 50 - 59 etc.

49 would be an upper class limit, but 49.5 would be an upper class boundary, since a reading of 49.4 for example falls outside the class limits.

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.


What is class width?

Class width, from statistics, is the difference between the two boundaries of a class. A class is an interval that includes all of the values in a (quantitative) data set that fall within two numbers, the lower and upper limits of the class. Finally, a class boundary is the midpoint of the upper limit of one class and the lower limit of the next class.


What is class interval size?

The class interval for each interval is the difference between its upper limit and its lower limit.


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 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 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 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


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.
