What is the meaning of class intervals in Maths data handling?
While arranging large amount of data (in statistics), they are grouped into different classes to get an idea of the distribution, and the range of such class of data is called the Class Interval.

    Class intervals are generally equal in width and are mutually exclusive.
    The ends of a class interval are called class limits, and the middle of an interval is called a class mark.
    Class interval is generally used to draw histogram.
