Secondary data often contains __________.

Secondary data often contains personal bias. This bias can arise from how data is collected, analyzed, and presented by the original researchers. When secondary data is utilized, it's important to consider the context in which it was gathered and any subjective interpretations that may have influenced its presentation. Researchers or organizations may have certain agendas or perspectives that shape the data, potentially affecting its neutrality and the conclusions drawn from it.

In contrast, options suggesting statistical significance and high reliability are generally attributes associated with well-designed primary research rather than secondary data. Moreover, primary sourcing refers to firsthand data collection, which is distinct from secondary data sourced from previously published research or reports. Thus, understanding potential biases in secondary data is critical for accurate analysis and decision-making in property management and other fields.
