Background

Once the researcher has validated his research instrument, the next job is data
collection. The more reliable and valid the source of data, the more authentic will be the
findings and conclusion of research. Data can be collected from two sources- primary
and secondary. When you collect the data for the first time by observing the world
around you, talking to people the data becomes primary. Alternatively, you can tap into
the vast wealth of information already collected by others, such as books and journals.
Then the data is called secondary data. Let us examine various sources of data and
different tools used for collecting data.
