Dear experts ,justify that data collection is the foundation of statistical investigation
For conducting any research or study, the first thing that is required is a set of facts or numerical figures. Any study cannot be initiated without the availability of a suitable data. For example, a study on the performance of the students in a school requires data related to the marks of the students. Similarly, a study on unemployment in a country requires numerical facts relating to unemployment. Thus, it can be said that a suitable and appropriate data forms the base of any study and research. The required data must be collected from one source or the other. Thus, we can say that data collection is the foundation of statistical investigation.
