在心理学中广泛使用置信区间（CI），特别是作为数字中的误差线，是一个可取的发展。然而，心理学家很少使用CI，可能不太理解它们。作者讨论了误差线图形的解释，并分析了CI与统计显著性检验的关系。他们提出了7条眼睛规则来指导对带有误差线的数字的推理使用。其中包括一般原则：寻找与感兴趣的效应直接相关的条形图，对实验设计敏感，并解释区间。它们还包括独立组平均值上CI重叠的推断解释指南。区间估计在心理学中的广泛应用有可能大大改善研究交流。
Wider use in psychology of confidence intervals (CIs), especially as error bars in figures, is a desirable development. However, psychologists seldom use CIs and may not understand them well. The authors discuss the interpretation of figures with error bars and analyze the relationship between CIs and statistical significance testing. They propose 7 rules of eye to guide the inferential use of figures with error bars. These include general principles: Seek bars that relate directly to effects of interest, be sensitive to experimental design, and interpret the intervals. They also include guidelines for inferential interpretation of the overlap of CIs on independent group means. Wider use of interval estimation in psychology has the potential to improve research communication substantially.
