对收集到的数据进行分析研究后得到的统计结果,往往更有利于揭示客观事物的本质及其规律.而值得注意的是,在忽视统计背景的前提下,本应科学合理的统计结果,有时会呈现出令人惊讶的反常态势.你不妨看看下面这个故事.在1972年至1974年间,英国进行了一项有关甲状腺疾病与心脏病的专题研究.20年后又进行了后续的追踪调查,于1996年作出的某份调查报告中对被调查妇女是否抽烟与被调查妇女是否存活的数据作了统计分析,部分数据如表1(死亡率精确到0.01%). The statistical results obtained after analyzing the collected data tend to be more conducive to reveal the essence and laws of objective things.While it is worth noting that under the premise of neglecting the statistical background, this should be scientific and reasonable statistical results, and sometimes You may wish to look at the following story: A special case study on thyroid disease and heart disease was conducted in the United Kingdom between 1972 and 1974. Follow-up follow-up investigations took place 20 years later , A survey conducted in 1996 made a statistical analysis of the smoking prevalence of the surveyed women and whether or not the women surveyed survived. Part of the data are shown in Table 1 (with an accuracy of 0.01%).
