Raw data是什麼意思

"Raw data" is a term used to describe data that has not been processed, cleaned, or analyzed. It is the most basic form of data that has been collected and typically requires further manipulation before it can be used for analysis or to draw conclusions. Raw data can come from a variety of sources, including surveys, experiments, sensors, and transactions, and it is often in a format that is not easily readable or understandable by humans.

For example, if you were to collect data from a survey about people's favorite colors, the raw data might include responses such as "blue," "green," "red," and so on. This data would need to be organized and potentially cleaned (e.g., to remove duplicate entries or incorrect data) before it could be used to calculate the most popular colors or to make any other meaningful observations.

Raw data is an important concept in fields such as statistics, data science, and computer science, where the goal is often to process and analyze large amounts of data to uncover patterns, trends, and insights.
