All About Data

摘要

We can't be certain, but Lt. Commander Data, a character on "Star Trek: The Next Generation," may have derived his name from his ability to acquire and process data critical to the mission of the United Star Ship Enterprise. Clearly, the series' production staff believed the importance of data would continue well into the future. As a quality practitioner, you owe it to yourself to gain a better understanding of the types of data, data stratification and data collection. Attribute data, also known as discrete data, are counted in whole numbers or integers. An attribute is the presence or absence of a particular characteristic. The result will always be a whole number-never a decimal fraction.
