In the sample investigation, the sampling error and the non- sampling error constituted the sample investigation total error together, between the two has presented this to disappear the other long relations, ordinary circumstances similarly hereinafter when reduced two kind of errors is extremely difficult, this could not but consider two kind of errors to the sample investigation influence. Generally speaking, the sampling error may beforehand calculate and performs control, but non- sampling error computation then relative quite is difficult. In certain situations, the non- sampling error even surpasses the sampling error to the sampling result influence. Already had the deeper rationale about the sampling error control, but regarding estimated the non- sampling error the influence still did not have one kind of comprehensive theory by and its the control method. Along with the social economy development, the sample investigation more and more receives people's attention, the non- sampling error also becomes in the sample investigation precision the noticeable influence factor. Based on such consideration, this article the reason and the influence which will produce from three aspects multianalyses non- sampling error, nearly will seek controls the non- sampling error the method
