Transcript of Describe and Evaluate the Use of Primary and Secondary data in Research

Secondary data, however, might have been gathered some time ago. It may no longer be generalisable to the current population and might not be valid as cultures change over time, as do people.

However..
Secondary data used in studies like meta-analysis can compare data from different sources and therefore it can be checked for reliability and validity.
And Finally...
Primary data is likely to be gathered at the time of the study and conclusions will then be drawn.
Primary data can be considered more trustworthy, as in it is more valid than secondary data. Primary is conducted with a chosen research method and design and is therefore more credible than secondary data.
Secondary data, on the other hand...
is likely to of been gathered for some other purpose than the one intended by the researcher. Often it has already been analysed which can then be subjective as it is analysed for one purpose it is not valid for another purpose.
Primary data is gathered first hand, following careful operationalisation or variables and using carefully chosen procedures.
Consideration is given to what is being gathered in terms of data so they are about 'real life'.
Operationalising the IV is done so that it represents what is to be measured.

In general, therefore, primary data should be valid because the study is designed and carried out for the main purpose of the research.
Primary data is expensive to obtain because each researcher or research team has to start from the beginning

Secondary data is cheaper because it already exists.

Primary Data
is gathered from a first-hand source, directly by the researcher.
For example Milgram (1963) and Bandura et al. (1961). Questionnaires, observations, content analysis, and experiments are all ways to gather primary data
.

Secondary Data
has already been gathered by someone for further research.
E.g. government statistics like a census or a meta-analysis like Harber and Harber (2001).
