Open-End Class Interval / Open-End Classes / Open-End Series
In an Open-End interval, the lower limit of the first interval and/or the upper limit of the last interval is not given. Here, the length of these intervals is merely guessed based on the length of the interval nearest to them. […]

Inclusive Series
Continuous series such as 5-9, 10-14, 15-19, 20-24… is called an inclusive series. In such an inclusive series, the upper limit of one class is not equal to the lower limit of the next class. […]

Exclusive Series
Continuous series such as 0-10, 10-20, 20-30… is called an exclusive series. In such an exclusive series, the upper limit of one class is the lower limit of the next class. […]
