To further complicate matters,one rarely if ever knows how large the complete data set would actually be with the result that it is never possible to know what percentage of the total data set is being brought to bear in the solution of the problem.There are countless examples in civil engineering and dam safety practice where just one extra piece of data (e.g.one more or a slightly deeper drill hole) would have led to a completely different conclusion.Thus,there is no way to demonstrate that sufficient data has been collected to form a mathematically valid approximation (or known degree of approximation) of the complete data set.Unere such circumstances,the best defence against a false sense of security is the sceptical approach of the inquiring mind.
Aside from the problem of the quantity of data,the quality of the data is extremely improtant and it is generally advisable to qualify the data in some way prior to accepting it for use in the analysis process.Without such a process of qualifying data,additional uncertainties and even errors will be introduced into the analysis.There are established procedures to qualify data to protect the integrity of the analysis process.The procedures used to qualify the data and information used in the analysis will normally be specified.

为了要更进一步弄复杂物质,一很少地如果曾经知道完全的数据组如何大大地会实际上由于结果知道从不是可能的总数据的什么百分比组正在被带来在问题的解决方面忍受.在土木工程中有数不尽的例子,而且水坝安全练习额外数据 (举例来说另外一个或一个些微比较深的钻孔机洞) 的块只是会导致一个完全不同的结论地方.因此,没有方法示范充份的数据已经被收集形成完全数据组的一个算术有效近似值 (或近似值的已知程度).Unere 如此的环境,最好的防卫反对一个假安全感是寻问思想的怀疑方式.
来自数据的量的问题的旁白,数据的质量是极端地 improtant 和它通常适当在为分析程序的使用接受它之前在某些方面取得资格数据.没有如此的取得资格数据,另外的不确定和平坦的错误的程序将会进入分析之内被介绍.有确定的程序取得资格数据保护分析程序的正直.程序过去一直通常取得资格数据和被用于分析的数据将会被指定.
