Definition: 
If, in a frequency distribution, the initial class interval is indeterminate at its beginning and/or the final class interval is indeterminate at its end, the distribution is said to possess “open ended” classes.
This feature is undesirable owing to its effect upon certain calculations which require the central value of the class interval, e.g. the power moments. On the other hand, it usually has no effect upon the calculation of the quantiles and in particular the median value of the variate.
