    The major difference lies in the data source.

    The biggest difference is in the data source. The former is primary data, that is, data based on your own surveys or experiments. The latter is to collect data from previous studies for integration.

    Primary research uses your own original data, and secondary research uses data collected through past researches.

    Primary data is a real-time data whereas secondary data is one which relates to the past. Primary data is collected for addressing the problem at hand while secondary data is collected for purposes other than the problem at hand.

    The major difference lies in the data source.

    The primary research records of original experiment, but the secondary research summaries of past related researches and comments on their findings.

    Data sources are the main difference.
