In the last incarnation of this column, we were reminded of the importance of accuracy, narrowly operationalized as understanding the difference between the population parameter (beta) and our estimate of that parameter through regression. Here, we will remind ourselves of the importance of meaning, operationalized as understanding the meaning of the magnitude of the difference in addition to its statistical significance.
在本专栏的上一期内容中，我们被提醒了准确性的重要性，这里将准确性狭义地定义为理解总体参数（β）与我们通过回归对该参数的估计之间的差异。在此，我们将提醒自己意义的重要性，这里将意义定义为除了理解差异大小的统计显著性之外，还要理解其大小的含义。
