1. Alligation medial is merely a matter of finding a weighted mean . 2. Another example of a weighted mean is the weighted harmonic mean. 3. However, this can be done using the Goldman-Hodgkin-Katz equation or the weighted means equation. 4. Scharr operators result from an optimization minimizing weighted mean squared angular error in Fourier domain. 5. Statistical analyses involving means, weighted means , and regression coefficients all lead to statistics having this form. 6. After having rounded the individual grades, a weighted mean is used to calculate the overall result. 7. Probably the best known weighted mean is the weighted arithmetic mean, usually simply called the weighted mean . 8. If all the weights are equal, then the weighted mean is the same as the arithmetic mean. 9. Probably the best known weighted mean is the weighted arithmetic mean, usually simply called the weighted mean. 10. With some values of the parameter, the value of assumes familiar kinds of weighted mean as special cases.
