Final answer:
Engineers at Eldorado Corporation organizing data on manufacturing defects by occurrence frequency for future quality improvement is an example of a histogram, which is a tool for visualizing data distribution.
Step-by-step explanation:
The engineers at Eldorado Corporation are sorting manufacturing defects in order of their frequency to analyze and enhance product quality. This kind of data organization and analysis is an example of a histogram.
A histogram is a graphical representation of data that shows the distribution of a dataset and is useful for showing the frequency of different categories of data. By collecting data on defects and organizing them into a histogram, the engineers can easily see which defects are most common and prioritize their quality improvement efforts accordingly.
Other tools mentioned, like the cause-and-effect diagram, process-flow analysis, and control chart, have different purposes in quality control and process management. A cause-and-effect diagram helps identify potential factors causing an issue. A process-flow analysis examines the steps in a process to find improvements. A control chart is used to monitor the consistency of process performance over time.
