In statistics, primary data refers to data that is collected directly from the source, rather than being gathered from secondary sources. This data is typically collected for a specific research purpose and is often collected by the researcher or a team working on the research project.
There are several methods of collecting primary data, including surveys, experiments, observations, and interviews. Surveys involve collecting data from a large number of individuals through written or oral questions. Experiments involve manipulating a variable in a controlled environment to observe the effect on a dependent variable. Observations involve studying and recording the behavior or characteristics of a particular group or phenomenon. Interviews involve collecting data through one-on-one conversations with individuals.

However, it is important to note that primary data collection can be time-consuming and costly, and may not always be feasible for every research project.
In summary, primary data is data that is collected directly from the source for a specific research purpose, using methods such as surveys, experiments, observations, and interviews. It is considered to be more reliable and accurate than secondary data, but may not always be feasible for every research project due to the time and cost involved in its collection.
