Distinguish between primary data and secondary data

An explanation of the differences between primary and secondary market research methods.

Conducting both secondary and primary research can help

Panel A (primary end point) and Panel B (first secondary end point) show the cumulative probability of clinical disability progression (as defined by an increase in the score on the Expanded Disability Status Scale) that was confirmed after at least 12 weeks and at least 24 weeks, respectively, in time-to-event analyses. P values were calculated with the use of the log-rank test.

This guide outlines the differences between primary, secondary and tertiary sources of information.

What is primary data and secondary data in ..

An advantage of using primary data is that researchers are collecting information for the specific purposes of their study. In essence, the questions the researchers ask are tailored to elicit the data that will help them with their study. Researchers collect the data themselves, using surveys, interviews and direct observations.

Primary data is raw information collected by researchers for a specific purpose

What are the advantages of using these two types of data? Which tends to take longer to process and which is more expensive? This column will help to explain the differences between primary and secondary data.

To take another example, let’s say a research team wants to find out about workers’ experiences in return to work after a work-related injury. Part of the research may involve interviewing workers by telephone about how long they were off work and about their experiences with the return-to-work process. The workers’ answers–considered primary data–will provide the researchers with specific information about the return-to-work process; e.g. they may learn about the frequency of work accommodation offers, and the reasons some workers refused such offers.

Distinguish Between Primary Data and Secondary Data

Researchers need to consider the sources on which to base and confirm their research and findings. They have a choice between primary data and secondary sources and the use of both, which is termed triangulation, or dual methodology.

What are examples of primary data and secondary data? - …

There are several types of secondary data. They can include information from the national population census and other government information collected by Statistics Canada. One type of secondary data that’s used increasingly is administrative data. This term refers to data that is collected routinely as part of the day-to-day operations of an organization, institution or agency. There are any number of examples: motor vehicle registrations, hospital intake and discharge records, workers’ compensation claims records, and more.

Primary Data (PD) is the information ..

Compared to primary data, secondary data tends to be readily available and inexpensive to obtain. In addition, administrative data tends to have large samples, because the data collection is comprehensive and routine. What’s more, administrative data (and many types of secondary data) are collected over a long period. That allows researchers to detect change over time.

Going back to the return-to-work study mentioned above, the researchers could also examine secondary data in addition to the information provided by their primary data (i.e. survey results). They could look at workers’ compensation lost-time claims data to determine the amount of time workers were receiving wage replacement benefits. With a combination of these two data sources, the researchers may be able to determine which factors predict a shorter work absence among injured workers. This information could then help improve return to work for other injured workers.
