Due to the different precision of the measured values, the weights used in the correction calculation are also different. The higher the accuracy, the greater the weight. The weight is "multiplied by the weight", that is, "multiplied by the coefficient".

The weight can reflect the accuracy between several observations of the same quantity, and can also reflect the accuracy between observations of different quantities. The average value is the sum of all numbers and then divided by the total number of these numbers, (p1+P2+P3+PN)/n. When calculating, if there are several identical numbers in that number, multiply this number by several times and add it up. The average is still divided by the total.
