Question

cannot be calculated in case of open end class distribution​

Answer 1

In case of open ended class intervals, it cannot be calculated without assuming the size of the open end classes.

Answer 2

Mean can not be calculated.

• It is one of the measures of central tendency.
• It is calculated as - Mean = sum of observations/Total number of observations.
• In such a series the intervals are missing, whereas in the case of mean there are no such intervals.
• Thus, it cannot be calculated in case of open end class distribution​
• It is one of the demerits of mean.
