Mean (or average) of observations, as we know, is the sum of the values of all the observations divided by the total number of observations. If x1, x2,… xn, are observations with respective frequencies f1, f2,, . . ., fn then this means observation x1, occurs f1 times, x2, occurs f2, times, and so on.

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.
