通过实验观察取得了一系列的原始数据,研究者的任务,不仅是收集这些实验资料(原始数据),而且必须对这些实验资料进行统计处理,然后进行分析和判断,并得出相应的实验结论或解释。对实验结果的判断,实际上就是作出估计,即从“样本”去估计“总体”。由于医学科学实验多半采用小样本,实验例数较少,实验误差较大,因而所谓结论,其实也是一种推

A series of raw data was obtained through experimental observation. The tasks of the researchers were not only to collect these experimental data (raw data), but also to conduct statistical processing on these experimental data, and then analyze and judge them, and come to the corresponding experimental conclusions. Or explain. The judgment of the experimental results is actually to make an estimate, that is, to estimate the “overall” from the “sample”. Since medical science experiments mostly use small samples, the number of experimental cases is small, and experimental errors are large, so the conclusion is actually a kind of push.
