A study on quality traceability of transmission assembling based on Kruskal-Wallis method

摘要

Along with the development of tracing technique, the acquired data turns to be increasingly three-dimensional and complicated in quality traceability of transmission assembling, which requests of offering more scientific tracing statistical method of conversion from date information to decision information. In the paper, a statistical method is put forward based on Kruskal-Wallis test in light of data feature, pointing out test steps of applying Kruskal-Wallis method and offering scientific referential ground to the next decision of directors according to traceability analysis on transmission assembling quality in the test. It is shown from the experimental results that application of Kruskal-Wallis takes effect in quality traceability of transmission assembling.
