Dr. Johnson. www.researchdemys 5 Secondary Analysis of Data In the planning phase, researchers should determine whether there is data they can use It is more efficient to use data collected by others if it meets the research requirements and is of high quality. For example: That National Longitudinal Survey of Youth collected data about drug use.

Dr. Johnson. www.researchdemys 6 Secondary Analysis of Data Large research studies gather data that is specifically related to the research questions and often gather other data that might be useful. The Framingham study focused on factors related to heart disease, tracking 5,000 people from 1983-2003. Other researchers used that data to look at why people are happy. Researchers Conclusion: happiness is contagious!

Dr. Johnson. www.researchdemys 7 Things to Consider Does the database contain the data needed to answer your research question? If the question is about drug use among high school seniors, then a study looking at drug use among adults will probably be inappropriate.

Dr. Johnson. www.researchdemys 8 Things to Consider How did they collect the data and does it meet research standards? How did they measure their key variables? Did they use documented procedures for selecting people, developing data collection instruments, and pre-testing?

Dr. Johnson. www.researchdemys 9 Things to Consider What quality control procedures were used to ensure the accuracy of the data in the database? What is the error rate? This means the difference between the data collected and the data in the database.

Dr. Johnson. www.researchdemys 10 Things to Consider How hard will it be to gain access to the data? Will the researchers provide all the documentation, including the data dictionary that specifies every variable and how every value for ever variable is coded? For example, are Men coded 1 and Women coded 2 or is it Women coded 1 and Men coded 2?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
