The harmonic mean is calculated as the number of values Ndivided by the sum of the reciprocal of the values (1 over each value). 1. Harmonic Mean = N / (1/x1 + 1/x2 + … + 1/xN) If there are just two values (x1 and x2), a simplified calculation of the harmonic mean can be calculated as: 1. Harmonic Mean = (2 * x1 * … See more This tutorial is divided into five parts; they are: 1. What Is the Average? 2. Arithmetic Mean 3. Geometric Mean 4. Harmonic Mean 5.

WebThe harmonic mean helps to find multiplicative or divisor relationships between fractions without worrying about common denominators. Harmonic means are often used in averaging things like rates (e.g., the average travel speed given a duration of several trips). ... Accuracy is used when the True Positives and True negatives are more important ... WebA harmonic impedance estimation method is proposed in this paper, which takes the Gaussian mixture regression (GMR) as the main idea, and is dedicated to calculating the harmonic impedance when the load changes or the background harmonic changes in the traction power supply system. henrico circuit court judges chambers
