40 results about "Weighted arithmetic mean" patented technology

The weighted arithmetic mean is similar to an ordinary arithmetic mean (the most common type of average), except that instead of each of the data points contributing equally to the final average, some data points contribute more than others. The notion of weighted mean plays a role in descriptive statistics and also occurs in a more general form in several other areas of mathematics.

The method enables the orchard to be divided into n land parcels according to different landforms, so as to distribute different numbers of sensors. Specifically, the number of sensors ofother land parcels is deduced through the first land parcel. The method reduces the blindness of the precise fertilization of the orchard, improves the laying accuracy and scientificity of the sampling points of the orchard, achieves the optimization of the number under the certain precision, saves the cost, and facilitates the implementation.
