“Data used in statistical study is termed as either “Primary” or “Secondary” depending upon whether it was collected specifically for the study in question or for some other purpose.” Explain both the sources of collecting the data in brief

Certainly! Let’s briefly explain both primary and secondary sources of collecting data:

  1. Primary Data:
  • Definition: Primary data refers to the data collected directly from the source for the purpose of a specific research study.
  • Collection Methods: This data is gathered firsthand through methods such as surveys, interviews, observations, experiments, or direct measurements.
  • Characteristics: It is original, specific to the research objective, and can provide current and relevant information.
  1. Secondary Data:
  • Definition: Secondary data refers to data that has been collected by someone else for a purpose other than the current research study.
  • Sources: It can be obtained from various sources such as government publications, reports, articles, books, and previously conducted research studies.
  • Characteristics: Secondary data is pre-existing, and researchers analyze and interpret it for their own study. It is often used when collecting new primary data is impractical or unnecessary.

In summary, primary data is collected directly for the current research, while secondary data is already available and is utilized for analysis in a different context than its original purpose. The choice between primary and secondary data depends on the research objectives, resources, and the specific requirements of the study.
