Primary Data
Primary data refers to the original data collected for a specific research purpose. It is collected directly from the source through methods such as surveys, experiments, and observations. Primary data is considered more reliable and accurate than secondary data, which is data that has already been collected and published by others. In data science, primary data is often used to train machine learning models and to gain insights into specific research questions. It can be collected through various methods such as online surveys, interviews, and sensor data. The collection and analysis of primary data can be time-consuming and expensive, but it provides valuable insights that cannot be obtained from secondary data alone.
