    Disadvantages of secondary data

    Finding data to suit the project

    May not be accurate

    May be outdated A number of assumptions has to be made

    USESOFSECONDARY DATA

    Enables better planning of primary research

    methods.

    Secondary data also help to define the

    population, select sample in primary

    information collection and define the

    parameters of primary research.

    It helps to define the problem and formulatehypothesis about its solution.
