It is least affected by the fluctuation of sampling, It can neither be determined by inspection or by graphical location, Arithmetic mean cannot be computed for qualitative data like data on intelligence honesty and smoking habit etc, It is too much affected by extreme observations and hence it is not adequately represent data consisting of some extreme point, Arithmetic mean cannot be computed when class intervals have open ends. The mean is affected by unusually large or small data values. endstream
