The mean is a measure of central tendency, and the three most common ways to calculate the mean are the arithmetic mean (sum the values and divide by the number of values, n); the geometric mean (multiply all the values and raise them to a power of 1/n, where n is again the number of values); and the harmonic mean, where you divide n (the number of values) by the sum of the reciprocals.
Using the examples where there are three values, 3, 5, and 7, the arithmetic mean would be: (3+5+7)/3 = 15/3 = 5; the geometric mean would be (3*5*7)^1/3 = cubed root of (3*5*7) = cubed root of 105 = 4.72; and the harmonic mean would be 3/(1/3 +1/5 +1/7) = 3/0.676 = 4.44. The geometric mean is best when taking the average of values that are normalized to a reference point (relative values). The harmonic mean is best when small values have more meaning than large value, such as in population genetics when a small number of individuals can put the population in a genetic bottleneck, where alleles are lost from the population, whereas large numbers of individuals do not cause this type of impact. The arithmetic mean is used most commonly, and applies under most circumstances as a good measure of central tendency.

What is a harmonic mean?
When applied to electrical waveforms, a 'harmonic' is a multiple of the fundamental frequency.
Is the harmonic series important for brass instruments?
Yes. The harmonic series is the foundation of how brass instruments work.
What does it mean if the harmonic balancer is wobbling on a 2004 2.7L Dodge Intrepid?
Harmonic balancer is bad and will need to be replaced.
What is the advantages and disadvantages of harmonic mean?
The advantage of harmonic mean is that it is used to solve situations in which there are extreme data values to true picture. The disadvantage of it is that it can be time consuming to evaluate the data.
Will a 350 harmonic balancer work on a 4.3L V6 and if not why?
No, a 350 harmonic balancer will not work on a 4.3L V6 because they have different specifications such as size, weight, and balance. Using the wrong harmonic balancer can cause vibrations, premature wear on engine components, and potential engine damage. It is important to use the correct harmonic balancer for your specific engine.

Will a Chevy 305 harmonic balancer work on a 350 motor?

What does histogram find out graphically arithmetic mean or median or mode or harmonic mean?
mode
Is motion of swing an example of simple harmonic motion?
A body undergoes simple harmonic motion if the acceleration of the particle is proportional to the displacement of the particle from the mean position and the acceleration is always directed towards that mean. Provided the amplitude is small, a swing is an example of simple harmonic motion.
WHAT IS relation between arithmetic mean geometric mean and harmonic mean of two numbers?
If x and y are two positive numbers, with arithmetic mean A, geometric mean G and harmonic mean H, then A ≥ G ≥ H with equality only when x = y.
What does homophony mean in music?
Music played in a harmonic, chordal texture.
