Alligation medial is merely a matter of finding a weighted mean.

Most forms of index number are essentially weighted means such as were described in Section 3.1.5.

Different commodities are combined as weighted means of the relative change ratios.

After having rounded the individual grades, a weighted mean is used to calculate the overall result.

If all the weights are equal, then the weighted mean is the same as the arithmetic mean.

Since only the relative weights are relevant, any weighted mean can be expressed using coefficients that sum to one.

In this event, the variance in the weighted mean must be corrected to account for the fact that is too large.

This is just a weighted mean of two values, the weights having been computed previously.

Inflation is a weighted mean, in accordance with the size of each land .
