关于计量测定和计算等方面的技术数据,在规定的精度范围以外的数字都应以取舍,有些单位在数据处理上,往往采用习惯的“四舍五入”法。笔者认为此法并不准确,其原因是:在一批数据的处理上,出现舍去、进入的机会即概率是不均等的。数据舍去的机会有4个(1,2,3,4),而进入的机会却有5个(5,6,7,8,9),为了对一批数据作出科学的处理,在数据处理上应坚持采用国家科委规定的数字修约法来进行数据处理。具体方法:即按四舍六入,逢五要考虑 With respect to technical data such as measurement and calculation, etc., figures outside the specified accuracy range should be selected, and some units often use the customary “round-off” method in data processing. The author believes this method is inaccurate. The reason is that in the processing of a batch of data, there is an unequal probability that the opportunity to discard and enter is unclear. There are 4 (1,2,3,4) opportunities for data discarded and 5 (5,6,7,8,9) opportunities for entering, in order to scientifically process a batch of data, The treatment should be based on the digital contraction method prescribed by the State Science and Technology Commission for data processing. Specific methods: that is, according to rounding off, every five to consider
