The analysis of covariance (ANCOVA) is a powerful analytic tool, but there continue to be abuses of the method. We review assumptions and illustrate legitimate uses of ANCOVA, and summarize statistical packages' approach to the method. Finally, we consider how ANCOVA is used in contemporary nursing research.
协方差分析（ANCOVA）是一种强大的分析工具，但该方法仍存在被滥用的情况。我们回顾了其假设条件并举例说明了ANCOVA的合理用法，总结了统计软件包对该方法的处理方式。最后，我们探讨了ANCOVA在当代护理研究中的应用。
