Secondary Data

Secondary research is done to research the data collection through the study of information which has already being researched from the hospital websites, articles, discharge and intake records or through primary research.

Secondary data using existing data, as related to new data that is being gathered or have been recently gathered. Information already exist on the topics that are being studied. In quantitative approaches, it is this knowledge that assists one with finding the hypothesis to be examined in the new research. It opens the door for the researcher to further explore and generate new questions for the study. This also allows the researcher to find gaps in the research process. Secondary data sources can be acquired via the

Official statistics are data collected and published by the government and its agencies. While some data are viewed as accurate, such as birth, death and marriage rates, other data are viewed as inaccurate, such as suicide and crime rates. Official statistics are usually published on a regular basis and are freely available. Large samples are used, providing levels of representativeness not available to academic researchers.

Official statistics are quantitative data produced by local and national government bodies, and can cover a wide range of behaviour including births, deaths, marriages and divorce, income, crime, and work and leisure. Official statistics can be produced as a by-product of the normal workings of a government department, but they can also result from research designed specifically to produce them.

Coverage error, the failure to give some persons in a target population a chance to be selected into the sample, was present in the survey because insecure areas were not represented. The survey attempted to mitigate coverage errors by conducting face to face interviews to eliminate the coverage bias introduced by phone interviews. The response rate was not reported in the methodology page. However, if the response rate was 25%, that would indicate that the 1,000-sample size was taken from 4,000 individuals. Whether response rate affects data quality is a matter of debate, yet, according to Hillygus, “multiple studies have found that lower response rates do not indicate the results are inaccurate” (Hillygus 42). The role response rates have on the accuracy of results is uncertain, but inclusion of it provides insight into the quality of the methods.

However, the current study is a secondary exploratory analysis data of the past investigation and does not participate in the dangerous procedure of the past research. Secondary data analysis could be defined as the use of prior research data in order to answer questions that differ from the original study (Szabo & Strang 1997). Using a secondary exploratory data analysis is a harmless methodology that allows scientists to investigate certain anomaly with out produce damage to participants.

Another method that could be used to assess the need is to use secondary data. For instance, attaining the recidivism rate of individuals after receiving services. In addition, obtaining a domestic violence report to see in which area is the highest.

Ethical consideration: Research methods will carry out secondary data collection and analysis which is conducted without bias, plagiarism and no permission is required from ethics committee to do this research. The main difficulty for secondary literature review, it should be reliable and valid source to assess or to form a conclusion for a research. Therefore it is important to undertake a research ethically passed by ethics committee (Homan, 1991).

Secondary analysis: a research method in which the data were collected for some other purpose but still are useful to the researcher.

In spite of these advantages, there are limitations to this. Although survey “can be used to collect data that is a representative of a larger population”, but in reality the representative samples are very difficult to obtain. A researcher might not always have access the

The final issue presented in using a secondary research method is quality. Based on the source of the data, if it is in the public domain and the source is a trustworthy one, than its more than unlikely that it’s deliberately incorrect. Also, more research is essential to see other types of data from a different stance as not always the full picture is presented regarding it. (Newby, 2010)

Because questionnaires only give a certain set of answers the respondents wanted answer may not be there. Official statistics are statistics produced by local and national government, government agencies and organisations all funded by the government. This also produces quantitative data; the advantages of this are published statistics are readily available and cost little or sometimes nothing to use and many government surveys are well planned and organised with detailed questionnaires or interview schedules so they meet the standards of
