What is the difference between primary and secondary data in statistics?

What is the difference between primary and secondary data in statistics? Correct Answer The former is collected from the field of the investigation while the latter is collected from a separate entity

Data collected directly from the field of purposeful investigation is primary data because it is directly used by the one who collects it. If the data, gathered by an agency or a person, is used by a different agency or person for some purpose- there is no direct link between the data and the person requiring it. Thus this is secondary data.

Statement I Big data refers to no precise quantity, but generally refers to data in the range of Petabytes and Exabyte, i.e. billions to trillions of records, all from various sources. Big data is generated much faster. than traditional data in much larger quantities.
Statement II Big data interests industries because they are able to learn more patterns and curious variances than smaller data sets, with the capability to provide valuable insights into consumer behaviour, weather systems, financial market activity, or other phenomena.
Statement III Various departments and product lines use various applications within most organisations and store data in separate datasets. These separate databases may contain similar data, but data from one data base to another is not always consistent. This is called data silo.
