Heya mate....here is ur answer....hope u understand...
●Arithmetic Mean: It is a value obtained by adding together all the items and by dividing the total by the number of items. It is also called average. It is the most popular and widely used measure for representing the entire data by one value.
》》Arithmetic mean may be either:
1. Simple arithmetic mean, or
2. Weighted arithmetic mean.
●●●Properties of Arithmetic Mean●●●
1. The sum of deviations of the items from the arithmetic mean is always zero i.e.
∑(X–X) =0.
2. The Sum of the squared deviations of the items from A.M. is minimum, which is less than the sum of the squared deviations of the items from any other values.
3. If each item in the series is replaced by the mean, then the sum of these substitutions will be equal to the sum of the individual items.
