What are class boundaries in frequency distribution?

What are class boundaries in frequency distribution?

As a result, the “class boundaries” are the numbers that separate classes without forming gaps. They will be the lower limits of classes as calculated for a frequency distribution. A cumulative frequency graph, or ogive is a line graph displaying the cumulative frequency of each class at its upper class boundary.

How do you find the upper and lower class boundaries?

The lower boundary of each class is calculated by subtracting half of the gap value 12=0.5 1 2 = 0.5 from the class lower limit. On the other hand, the upper boundary of each class is calculated by adding half of the gap value 12=0.5 1 2 = 0.5 to the class upper limit.

What is the upper boundary of the lowest class interval?

5 and 15 are called the class limits of the class interval 5 – 15: 5 is the lower limit and 15 is the upper limit of the class. Similarly, 15 and 30 are the respectively lower limit and upper limit of the class interval 15 – 30.

What is the upper class limit?

The upper class limit of a class is the largest value that can appear in that class. The class width is the difference between consecutive lower class limits.

What is the upper class limit of 25 30?

Answer. Answer: The upper limit is 30.

What is the upper class boundary of the top interval?

Answer and Explanation: The class interval (23-35) is given where 23 is the lower-class limit and 35 is the upper-class limit of the interval.

What is the lower class limit in the 20 30?

20
Answer: In the class interval 20 – 30, the lower class limit is 20.

What is upper and lower limit?

Upper limit is the highest value of the class interval. Similarly, the lower limit is the smallest value of the class interval. For finding the actual upper limits and actual lower limits , we need to make the upper limit of a certain class and lower limit of the next class to be equal and same for the lower limit.
