Question
Under what circumstances are median mostly used to measure central tendency?
Solution
1. In open ended series, median and mode can be easily calculated, while it is difficult to compute arithmetic mean, because it is not possible to calculate mid-pqjnts of these class intervals.
2. Median and Mode are not affected by extreme values while arithmetic mean is affected by extreme values.
3. Median and Mode can be calculated graphically, while there is no graphical method for calculating arithmetic mean.
