英语翻译
A histogram is a graphical representation of data as a frequency distribution.This tool is valuable in evaluating both attribute (pass/fail) and variable (measurement) data.Histograms offer a quick look at the data at a single point in time; they do not display variance or trends over time.A histogram displays how the cu- mulative data look today.It is useful in understanding the relative frequencies (percentages) or frequency (numbers) of the data and how those data are distributed.Figure 20-15 illustrates a histogram of the frequency of defects in a manufacturing process.

柱状图是将数据以图形化的形式表达其频率的分布;此工具有助于评价属性数据(通过与否)和可变数据(测量).使用柱状图可以快速查看某个时间点的数据,但随时间的变化或趋势却不显示;柱状图只展示目前的累积数据.对于想了解数据的相对频率(百分比)或频率(数字)以及这些数据是如何分布的,柱状图是十分有用的.图表20-15 展示生产过程中缺陷频率的柱状图.
