The cubic mean (written as ) is a specific instance of the generalized mean with .
For real numbers the cubic mean is defined as:
For example, the cubic mean of two numbers is:
The cubic mean is used to predict the life expectancy of machine parts. [3] [4] [5] [6]
The cubic mean wind speed has been used a measure of local potential for wind energy. [7]
The cubic mean is also used in biology to measure the mean dimensions of spherical bacteria ( cocci) [8] and of larger animals that are approximately spheroidal in shape. [9] In this case using the conventional arithmetic mean will not give an accurate result because the size of a spherical bacterium increases as the cube of the radius.
