which of the following do researcher mean by secondary data

information from research aleady conducted for another purpose
data collected specifically for the researchers own study
data considered less important than primary data
data collected after any research to gather primary data

Researchers typically mean "information from research already conducted for another purpose" when referring to secondary data. Secondary data refers to data that has been collected by someone else for a different research project or study and is now being used by another researcher for their own purposes. It is considered as a valuable resource for conducting new analyses and generating new knowledge.

Researchers often refer to secondary data as information that has been already collected for a different purpose or by someone else. It is not collected specifically for the researcher's own study but can be utilized to answer research questions or support the findings. Secondary data is considered distinct from primary data, which is collected firsthand by the researchers themselves. It is also different from data collected after primary research to gather supplementary information or data.

Researchers mean information from research already conducted for another purpose when they refer to secondary data. Secondary data is data that has been collected by someone else or for a different research study. It can be derived from various sources such as previous studies, government reports, surveys, or databases.

To find secondary data, researchers can start by conducting a literature review to identify relevant studies or sources that have already been published. They can also explore various online databases, such as academic journals, government databases, or research repositories, to access secondary data that aligns with their research question or objective.

Once researchers have identified the most appropriate sources, they can extract and analyze the secondary data to address their research questions or hypotheses. By utilizing existing data, researchers can save time, resources, and effort compared to collecting data from scratch, particularly when the required data is already available and relevant to their study.
