introduction

A researcher does not use the data used in researches arbitrarily; this instead he compiles them with
the help of different tools and techniques. For scientific researches this data needs to be authentic and
to maintain this authenticity, researcher collects the data objectively. it is clear that for research, it is
very necessary to have authentic data and material.

10.1 Data collection and primary and secondary Data

for any survey or research, collection of data is very important. Until the facts related to the research
are not collected using the specific techniques, neither results can be made based on research, nor can
any type of rules be rendered. Data collection is an important step of the research process. the way
a building cannot be constructed without bricks, lime, stone, cement, gravel, wood and iron, in the
same way, the work of research cannot be completed without facts. To reach any scientific conclusion
and for generalization and principalisation receiving and collecting news, to know quantitative and
qualitative things are important. For example, if we want to know,children of which particular field
are more criminal in nature than others, in that case, research on children of both fields, their social
,economic, political, and religious conditions, their way of living, source of livelihood, process of
socialization of children have to done.
