摘要

由于种群成员之间的差异,大多数生物系统都存在固有的变异性。研究中通常会观察到两种类型的变异:样本间的差异和根据样本估计群体参数(如平均值)时的 "误差"。虽然这两个概念从根本上说非常不同,但相关的变异通常使用类似的符号来表示--一个区间,代表一个有下限和上限的数值范围。本文将讨论常见区间的使用(和误用)方式。

Depicting variability and uncertainty using intervals and error bars.

Variability is inherent in most biological systems due to differences among members of the population. Two types of variation are commonly observed in studies: differences among samples and the "error" in estimating a population parameter (e.g. mean) from a sample. While these concepts are fundamentally very different, the associated variation is often expressed using similar notation-an interval that represents a range of values with a lower and upper bound. In this article we discuss how common intervals are used (and misused).

期刊介绍: The international journal of laboratory animal science and welfare, Laboratory Animals publishes peer-reviewed original papers and reviews on all aspects of the use of animals in biomedical research. The journal promotes improvements in the welfare or well-being of the animals used, it particularly focuses on research that reduces the number of animals used or which replaces animal models with in vitro alternatives.
