. Arithmetic mean questions


Best Answer

Arithmetic mean is similarly known as the mean or arithmetic average. It is calculated by adding all of the numbers in a given data set after which dividing it by the total range of items inside that set. The arithmetic mean (AM) for evenly distributed numbers is same to the middlemost number. Further, the AM is calculated using several methods, which is primarily based totally on the amount of the data, and the distribution of the data.

Formula of Arithmetic Mean

Mean (x̄) = Sum of all observations / Number of observations

Formula of Arithmetic Mean

For Example: Compute the arithmetic mean of the first 7 odd, natural numbers.

Solution: The first 6 odd, natural numbers: 1, 3, 5, 7, 9, 11,13

x̄ =ungrouped data49/7 = 7.

Hence, the arithmetic mean is 7.
