4) It is capable of being treated mathematically hence it is widely used in statistical analysis.

5) Arithmetic mean can be computed even if the derailed distribution is not known but some of the observation and number of the observation are known.

6) It is least affected by the fluctuation of sampling.

7) For every kind of data mean can be calculated.

Demerits of Arithmetic mean :

4) Arithmetic mean can not be computed when class intervals have open ends.

5) If any one of the data is missing then mean can not be calculated.
