Secondary data analysis
Examples of work classified in this way will be described; some cells remain empty (cells 1c, 2a and b, 3a and c) because appropriate examples have not yet been identified and it is not known if these forms of secondary analysis have ever been conducted (there are no a priori grounds for excluding them). Secondary data analysis involves an individual using the information that someone else gathered for his or her own purposes. Definition, methods & al diversity in the workplace: definition, trends & of measurement: nominal, ordinal, interval & has taught collegiate mathematics and holds a master's degree in pure this lesson, we'll define secondary data and secondary data analysis.
Other parts of analyzing secondary data include the following:Determining which of the data you collected is associated with your project (what data can be used). 1997) 'the possibilities and pitfalls of doing a secondary analysis of a qualitative data set', qualitative health research, vol. Although it should not be your sole type of data and analysis when conducting research, it is a perfect addition to primary data to make for a thorough and complete research er for a free you a student or a teacher?
I have adopted this strategy in my ongoing doctoral research which involves re-examining qualitative data relating to people's experiences of hospital discharge in order to explore the temporal organisation of this process and associated aftercare regimes (cell 3b). Primary data is information that is gathered by an individual or company for a specific purpose. It should also be noted that use of the approach does not necessarily preclude the possibility of collecting primary data.
Also, the data posted usually cleaned by professional staff members provide detailed documentation about the tion and data cleaning process. However, a number of practical and ethical considerations have been highlighted (hinds, vogel and clarke-steffen 1997, szabo and strang 1997, thorne 1994) and four key issues are summarised ibility of the data with secondary analysis: are the data amenable to secondary analysis? Third important advantage of using secondary data is that the data collection process often maintains a level of expertise and professionalism that may not be present with individual researchers or small research projects.
Arguments in favour of developing secondary analysis of qualitative studies have been put forward (hinds, vogel and clarke-steffen 1997, sandelowski 1997, szabo and strang 1997, thorne 1994). Of independent and dependent to calculate mean, median, mode & zing and understanding data with tables & tanding bar graphs and pie g and interpreting line ng & interpreting scatterplots: process & is a histogram in math? As will be shown below, secondary analysis can involve the use of single or multiple qualitative data sets, as well as mixed qualitative and quantitative data sets.
Difficulties notwithstanding, forms of secondary analysis are cross-classified in table 1 according to the focus of the analysis and the nature of the original data used. Introduction to secondary data introduction to survey tative data e the methods types for policy and uction to applied ogical analysis of historical census data us... Thirdly, there should be greater consideration of the issues involved in the secondary analysis of single, multiple and mixed data sets.
Someone else has already collected the data, so the researcher does not have to devote money, time, energy and resources to this phase of research.

Therefore,They are probably unaware of study-specific glitches in the data collection process that may ant to the interpretation of specific variables dataset.
Sometimes the secondary data set must be purchased, but the cost is almost always lower than the expense of collecting a similar data set from scratch, which usually entails salaries, travel and transportation, office space, equipment, and other overhead addition, since the data is already collected and usually cleaned and stored in electronic format, the researcher can spend most of her time analyzing the data instead of getting the data ready for analysis. For instance, in their secondary analysis of related quantitative and qualitative data sets about claimants of invalid care allowance, mclaughlin and ritchie (1994) concentrate on the ex-carers in the original sample in order to describe the socio-economic and psychological legacies of care giving among this group (cell 2c). Hence within the research team the data still has to be contextualised and interpreted by those who were not present.
There are irb-approved written policies and operating procedures for a repository or data management center that prohibit the release of the key to the investigators under any circumstances, until the individuals are deceased; or. Typical mental health research project begins with pment of a comprehensive research is (hopefully) followed by the successful funding; the researcher then collects data, results, and writes-up one or more research r less common, but no less important, is the analysis of existing data. Work to develop the approach is required in order to see if the potential benefits can actually be realised in gh the secondary analysis of quantitative data is a common and generally accepted mode of inquiry, the same cannot be said of qualitative data (hinds, vogel and clarke-steffen 1997).
Furthermore, as was shown above, existing studies have mainly been conducted by researchers re-using their own data rather than by independent analysts using data collected by others. Census data that the government gathers regularly about information, such as the population's age, highest level of schooling achieved, and economic information represents a source of secondary data.
