(statistics, probability) The measure of central tendency of a set of values computed by dividing the sum of the values by their number; commonly called the mean or the average.

(mathematics) A measure of central tendency of a set of n values computed by extracting the nth root of the product of the values.

(mathematics) A type of average calculated as the arithmetic mean of the squares of the values divided by the arithmetic mean of the values, ie. C=(x_1²+x_2²+...+x_n²)/n/(x_1+x_2+...+x_n)/norC(x_1,x_2,...,x_n)=x_1²+x_2²+...+x_n²/x_1+x_2+...+x_n

Alternative form of meantime / A mean (average) amount of time.

(statistics) The mean (usually arithmetic, but possibly geometric) of all members of a population or all possible values from which a sample can be taken, as opposed to a sample mean.

A position of balance between excess and deficiency.

(idiomatic) To be loved or cared about a great deal by.

(mathematics) A type of average, calculated as the square root of the mean of the squares, ie. Q=√x_1²+x_2²+...+x_n²/n.

(mathematics) A type of measure of central tendency calculated as the reciprocal of the mean of the reciprocals, ie, H=n/1/x_1+1/x_2+⋯+1/x_n

(astronomy, celestial mechanics) An orbital parameter of a celestial body (in an elliptic orbit); the mean motion multiplied by the time since the last passage through periapsis; the angle PCM (measured in radians) defined by P = the periapsis, C = the center of the elliptical orbit, and M = the mean planet.
