Answer 1

Examining data someone else has collected is an example of secondary analysis.

Secondary analysis involves the re-analysis of data (qualitative or quantitative) that was collected before in a previous study. Secondary analysis may be performed by the same researcher that collected the data initially or by another researcher. The data is analyzed and used to work on a new research of interest that is different from that of the original work.
