TYPES OF DATA

1) PRIMARY DATA:
       ·         Are those which are collected a fresh and for the first time and thus happen to be original in character and known as Primary data.
       ·         There are several methods of collecting primary data, particularly in surveys and descriptive researches. In descriptive research, we obtain primary data either through observation or through direct communication with respondents in one form or another or through personal interviews
2) SECONDARY DATA :
   Are those which have been collected by someone else and which have already been passed through the statistical process are known as Secondary data.
      These are already available i.e. they refer to the data which have already been collected and analyzed by someone else.
   Secondary data may either be published or unpublished data. Researcher must be very careful in using secondary data, because the data available may be sometimes unsuitable.
