有关直方图峰值众数计算新方法的探讨

he research that application of the histogram of quality determine new methods involve the calculation of the mode. In the single-peak of conditions, two kinds of distribution patterns that symmetric patterns and asymmetric patterns existed in the histograms of objective. Histogram is practical equivalency that in the asymmetric conditions of the skewed distribution. The calculation of skew distribution of mathematical expectation value is group central-value, it is clearly inconsistent with the traditional calculating method of the mode-group histogram. As appear on the lack of the discrepancy, the histogram new methods of calculating mode is deduced base on the calculation mode of Gaussian distribution theory about left expected deviation and right expected deviation.
