These 2 data types are very useful in research and statistics, but for the sake of this article, we will be restricting our scope to secondary data. We will study secondary data, its examples, sources and methods of analysis.

Literature Review Basics

Primary source material presents an original study. It is a first-hand account of research written by those who conducted it. Primary source material generally:.

ESL Placement and Schools. Educational Policy , 23 2 , In this study , the authors explore English as a Second Language ESL placement as a measure of how schools label and process immigrant students.

In schools with more immigrant students, the authors find that ESL placement results in higher levels of academic performance; in schools with few immigrant students, the effect reverses. This is not to suggest a one-size-fits-all policy; many immigrant students, regardless of school composition, generational status, or ESL placement, struggle to achieve at levels sufficient for acceptance to a 4-year university. This study offers several factors to be taken into consideration as schools develop policies and practices to provide immigrant students opportunities to learn.

Now, take a look at an example of secondary source material :. Ernst-Slavit, G. Ernst-Slavit et al provide teachers with selected background knowledge and strategies that enhance the learning process for English as a Second Language ESL students in secondary classrooms. With the changing U. Also discussed are the stages of language development and cultural adaptation that all second-language learners navigate through. Important linguistic and cultural processes are outlined and effective activities are suggested for students in various stages within those processes.

Secondary Sources. Social Research Methods. Start Here. Primary vs. Secondary Source Material Primary source material presents an original study. Primary source material generally: contains mention of methodology, presents data, presents findings and discusses those findings.

Secondary source material can be found in: literature reviews, which "try to make sense of all of the research that has been done in a given area" Perry , position papers, which propose answers or form hypotheses that can be tested by subsequent primary source studies, books, such as textbooks that try to summarize the literature of a given field. Is it Primary or Secondary Source Material? Consider these examples, taken from the following articles' abstracts.

First, an example of primary source material : Callahan, R. Now, take a look at an example of secondary source material : Ernst-Slavit, G. Report a problem. Subjects: Anthropology , Criminology , Psychology , Sociology.

Primary Sources of Data and Secondary Sources of Data

In some research, the researchers might use territory data but the reliability and validity of research decrease with the use of lesser authentic data. Hence it is important to understand the advantages, but also the pitfalls of studying religion Here's a shortened example of a research article that MIGHT have been written. One example of where medians have been used in preference to means is in reporting salaries. PDF generated using the open source mwlib toolkit.

Metrics details. The data from individual observational studies included in meta-analyses of drug effects are collected either from ad hoc methods i. The use of secondary sources may be prone to measurement bias and confounding due to over-the-counter and out-of-pocket drug consumption, or non-adherence to treatment. In fact, it has been noted that failing to consider the origin of the data as a potential cause of heterogeneity may change the conclusions of a meta-analysis. We aimed to assess to what extent the origin of data is explored as a source of heterogeneity in meta-analyses of observational studies. We evaluated, when reported, the type of data source primary vs secondary used in the individual observational studies included in each meta-analysis, and the exposure- and outcome-related variables included in sensitivity, subgroup or meta-regression analyses. We found articles, 23 of which fulfilled our eligibility criteria.

Social Research Methods

In a time when data is becoming easily accessible to researchers all over the world, the practicality of utilizing secondary data for research is becoming more prevalent, same as its questionable authenticity when compared with primary data. These 2 types of data, when considered for research is a double-edged sword because it can equally make a research project as well as it can mar it.
