In the Poisson distribution, this quantity is equal to the variance. This quantity is undefined for the Cauchy distribution, and for a binomial distribution, it is equal to the probability of success times the number of trials. One variety of this quantity is equal to the sample size divided by the sum of the reciprocals of those values, the "harmonic" type. This quantity is denoted by an "x" with a bar over it for a sample, and for a population, it is denoted by the Gre

One variety of this quantity is equal to the sample size divided by the sum of the reciprocals of those values, the "harmonic" type. This quantity is denoted by an "x" with a bar over it for a sample, and for a population, it is denoted by the Greek letter "mu." For 10 points, name this quantity whose arithmetic variety is equal to the sum of a set of values divided by the number of values.
