Abstract

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).

使用区间和误差条描述可变性和不确定性。
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。

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.
