The quadratic mean is a measure of the spread of values about their arithmetic mean. By definition, the arithmetic mean of the differences will be zero and so adds no information. Another measure is required and that is the quadratic mean.
Properties of Arithmetic Mean?
They are averages of different kinds: arithmetic mean, geometric mean, harmonic mean are three commonly used means.
The arithmetic mean is a weighted mean where each observation is given the same weight.
An adjective form is arithmetic, or arithmetical. They mean of or based on arithmetic.
it is a Greek word meaning the Science of Numbers or the Art of CountingThe word arithmetic is a noun. Its definition signifies it as the specific branch of math that deals with numbers only.
It is the sum of all of the numbers, divided by the number of numbers. For example, what is the arithmetic mean of this set of numbers: 8, 6, 4, 2 ? Add up the numbers: 8+6+4+2=20. The number of numbers is 4; so divide 20 by 4 to get 5, which is the arithmetic mean.
1.The Geometric mean is less then the arithmetic mean. GEOMETRIC MEAN < ARITHMETIC MEAN 2.
The arithmetic mean of a single number, such as 1784298281, is the number itself.

when is it appropriate to use arithmetic mean as opposed to median
The arithmetic mean of one number, such as 104410231017 is still simply that number.
You need to have all the values within the range to calculate the arithmetic mean .
arithmetic mean is the average (175+235) / 2 = 205
Any two numbers can have only one arithmetic mean. If the numbers are x and y, then their arithmetic mean is (x + y)/2.
There are a great number of advantages and disadvantages of Arithmetic mean. One disadvantages is that it is not accurate.
The difference between arithmetic and geometric mean you can find in the following link: "Calculation of the geometric mean of two numbers".
An arithmetic-geometric mean is a mean of two numbers which is the common limit of a pair of sequences, whose terms are defined by taking the arithmetic and geometric means of the previous pair of terms.
A method or process of computation with figures. the elementary branch of mathematics
The arithmetic mean is more commonly known as the average. It is the sum of the values divided by the number of values.
It is not possible to place 8 arithmetic means between two numbers since they can have only one arithmetic mean not eight! The one-and-only arithmetic mean of 2 and 17 is (2+17)/2 = 9.5
