Secondary analysis of existing sources involves using data that is already available, such as from government reports or previous studies. This saves time and expense of data gathering, but the researcher has no control over possible data bias because they did not collect the data themselves. The other options (experiment, survey, participant observation) all involve primary data collection, which can be more time-consuming and potentially biased if not conducted carefully.
