Plotting data into graphs is a crucial step in data analysis as part of an initial descriptive statistics exercise since it gives the researcher an overview of the shape and nature of the data. Outlier values may also be identified, and these may be incorrect data, or true and important outliers. This paper explains how to access Microsoft Excel's Analysis Toolpak and provides some pointers for the utilisation of the histogram tool within the Toolpak.
将数据绘制成图表是数据分析中作为初始描述性统计练习一部分的关键步骤，因为它能让研究人员对数据的形状和性质有一个总体了解。异常值也可能被识别出来，这些可能是错误的数据，或者是真实且重要的异常值。本文解释了如何访问微软Excel的分析工具库，并提供了一些关于在该工具库中使用直方图工具的提示。
