Merits And Demerits Of Arithmetic Mean. AM is too much affected by extreme values of the series. It is the basis of statistical analysis and analyze the data. Thanx and Enjoy the videos. AM is not applicable for qualitative data.
It also helps to obtain a picture of a complete group. L-It can neither be determined by inspection or by graphical location 2-Arithmetic mean cannot be computed for qualitative data like data on intelligence honesty and smoking habit etc 3-It is too much affected by extreme observations and hence it is not adequately represent data consisting of some extreme point. It is easy to understand and easy to calculate. DEMERITS OF ARITHMETIC MEAN l It can neither be determined by inspection or by graphical location l Arithmetic mean cannot be computed for qualitative data like data on intelligence honesty and smoking habit etc l It is too much affected by extreme observations and hence it is not adequately represent data consisting of some extreme point. It is a mathematical mean. The main purpose of average is to present a simple and systematic description of the data.
It also helps to obtain a picture of a complete group.
The arithmetic mean or simply mean of a sample is the sum of the sampled va lues divided by the number of items in the sample. As every item is taken in calculation it is effected by every item. It is the basis of statistical analysis and analyze the data. It is a mathematical mean. Some important properties of the arithmetic mean are as follows. Merits and demerits of Arithmetic mean Merits It is rigidly defined.
