Explanation:
In statistics the assumed mean is a method for calculating the arithmetic mean and standard deviation of a data set. It simplifies calculating accurate values by hand. Its interest today is chiefly historical but it can be used to quickly estimate these statistics. There are other rapid calculation methods which are more suited for computers which also ensure more accurate results than the obvious methods.
Arithmetic Mean
The first concept to understand from Mean Median and Mode is Mean. Mean is simply defined as the ratio of the summation of all values to the number of items. Note that there are two types of the arithmetic mean which are simple arithmetic mean and weighted arithmetic mean.
Mean = ∑X ÷ N
Here, ∑X= Sum of all the individual values and N= Total number of items
The simple arithmetic mean considers all the values in data as equal and grants equal importance to each value. Whereas, in weighted arithmetic mean weights or importance is assigned to the values. Without further delay let us study methods of constructing mean.
