Final answer:
Secondary research offers the advantages of being cost-effective and time-saving, as it utilizes preexisting data, which eliminates the need for new data collection. This can lead to substantial resource savings for researchers.
Step-by-step explanation:
The advantages of secondary research include cost-effectiveness and being time-saving. Secondary research refers to the use of already existing data gathered by someone else rather than collecting new data, which often involves substantial effort and resources. This approach can help researchers save money since they do not need to invest in the processes of data collection, such as recruiting participants, designing studies, or collecting data firsthand. It saves a significant amount of time, as the data collection has already been completed, and the researcher can immediately start analyzing the existing data for their specific needs. However, one should note that secondary research data may not always be perfectly tailored to the current research needs.
