摘要

当第一次接触主成分分析时，学生有时会错过分析的主要目的。通常只关注数据缩减，而忽略了数据缩减维度后该做什么。这里讨论的数据集可以用作课堂示例、家庭作业或书面项目，本文的重点是作为课堂示例。这些数据使学生有机会对不一定最容易处理的真实数据集进行主成分分析和后续分析。

Punching a Ticket to Cooperstown

ABSTRACT When exposed to principal components analysis for the first time, students can sometimes miss the primary purpose of the analysis. Often the focus is solely on data reduction and what to do after the dimensions of the data have been reduced is ignored. The datasets discussed here can be used as an in-class example, a homework assignment, or a written project, with a focus in this article as an in-class example. The data give the students an opportunity to perform principal components analysis and follow-up analyses on a real dataset that is not necessarily the easiest to handle.

期刊介绍： The "Datasets and Stories" department of the Journal of Statistics Education provides a forum for exchanging interesting datasets and discussing ways they can be used effectively in teaching statistics. This section of JSE is described fully in the article "Datasets and Stories: Introduction and Guidelines" by Robin H. Lock and Tim Arnold (1993). The Journal of Statistics Education maintains a Data Archive that contains the datasets described in "Datasets and Stories" articles, as well as additional datasets useful to statistics teachers. Lock and Arnold (1993) describe several criteria that will be considered before datasets are placed in the JSE Data Archive.
