对数据和指标的统计学处理问题,是医学科学论文写作中经常遇到的问题。如果这个问题不解决好,就会直接影响论文的质量,甚而可能导致错误的结论。故此,学会正确运用医用数理统计方法,对于每个立志献身医学科学的工作者来说都是必要的。我们知道,医学科学研究所得到的各种数据,可分为计量数据与计数数据两大类。前者是指计算定量指标者,后者是指计算定性指标者。计量数据的资料,一般是计算均数。均数是绝对指标,是各变量总和的平均值,可说明一套变量值的综合特征和集中趋势,反映总体的典型特征。当数据是呈正态分布
The problem of statistical processing of data and indicators is a problem often encountered in the writing of medical science papers. If this problem is not solved, it will directly affect the quality of the paper and may even lead to erroneous conclusions. Therefore, it is necessary for every worker who is determined to devote to medical science to learn how to correctly use medical statistics methods. We know that various kinds of data obtained by medical science research can be divided into two categories: measurement data and count data. The former refers to the calculation of quantitative indicators, while the latter refers to the calculation of qualitative indicators. The data of measurement data is generally the calculation of the mean. Mean is the absolute index, which is the average of the sum of the variables. It can explain the comprehensive characteristics and concentration trend of a set of variable values and reflect the typical characteristics of the overall. When the data is normally distributed
