The correct answer is: B. Close ended class
A close-ended class is a class in which the upper limit is treated as the lower limit of its next class. This means that there is no gap between the classes. For example, a class with the upper limit of 10 and the lower limit of 11 would be a close-ended class.
An open-ended class is a class in which the upper limit is not treated as the lower limit of its next class. This means that there is a gap between the classes. For example, a class with the upper limit of 10 and the lower limit of 12 would be an open-ended class.
An exclusive class is a class in which a value can only belong to one class. For example, a class of “male” and a class of “female” would be exclusive classes.
An inclusive class is a class in which a value can belong to multiple classes. For example, a class of “adult” and a class of “child” would be inclusive classes.
In the case of classification of data, the class having its upper limit is treated as the lower limit of its next class is called a close-ended class. This is because the upper limit of a close-ended class is not considered to be a separate class. Instead, it is considered to be the lower limit of the next class. This means that there is no gap between the classes.
