What is class boundary?

What is class boundary?

Class boundary is the midpoint of the upper class limit of one class and the lower class limit of the subsequent class. It must be noted that upper class boundary of one class and the lower class boundary of the subsequent class are the same. Class boundaries are not a part of the dataset.

What are the boundaries of the class 12 16?

Class Boundaries are the midpoints between the upper class limit of a class and the lower class limit of the next class in the sequence. For the class, 12 – 16, The lower class… y is the midpoint between 11 and 12, that is 11.5 . The upper class boundary is the midpoint between 16 and 17, that is 16.5 .

How do you find the lower boundary of grouped data?

The lower class boundary is found by subtracting 0.5 units from the lower class limit and the upper class boundary is found by adding 0.5 units to the upper class limit. The difference between the upper and lower boundaries of any class.

How do you find the upper boundary?

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. Simplify the lower and upper boundaries columns.

How do you find the class boundary from mid value?

To calculate the class interval, first step is to rewrite the table by including the values of mid-interval in place of the values given in range. Then the sum of all the mid- interval values is calculated.

What is the upper class boundary of the class 23 35?

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 boundary of class 50 59?

Class limit: In the class interval, say (10 – 19) is called the lower class limit and 19.5 is called the upper class limit….Solution:

Class-intervals Actual class interval Frequency
20 – 29 19.5 – 29.5 10
30 – 39 29.5 – 39.5 20
40 – 49 39.5 – 49.5 5
50 – 59 49.5 – 59.5 15

What is a lower class boundary?

The lower class boundary of a class is defined as the average of the lower limit of the class in question and the upper limit of the previous class. The upper class boundary is defined as average of the upper limit of the class in question and the lower limit of the next class.

How do you find the lower boundary?

The lower class boundary of a given class is obtained by averaging the upper limit of the previous class and the lower limit of the given class. The upper class boundary of a given class is obtained by averaging the upper limit of the class and the lower limit of the next class.

Which is an example of a class boundary?

Class Boundaries Class Boundaries are the midpoints between the upper class limit of a class and the lower class limit of the next class in the sequence. It is 0.5 more or less of a class limit. Therefore, each class has an upper and lower class boundary. Example: Class Frequency 300 – 399 13 400 – 499 20

Which is the midpoint of a class boundary?

Class Boundaries are the midpoints between the upper class limit of a class and the lower class limit of the next class in the sequence. It is 0.5 more or less of a class limit. Therefore, each class has an upper and lower class boundary.

Which is the class boundary of 0 – 9?

The class boundary of 0 – 9 is Upper class boundary = (upper-class limit of the concerned class + lower class limit of the subsequent class)/2

How is the upper boundary of a class calculated?

The lower boundary of each class is calculated by subtracting half of the gap value 1 2 = 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 1 2 = 0.5 1 2 = 0.5 to the class upper limit. Simplify the lower and upper boundaries columns.
