data source triangulation

Triangulation of Data Sources Qualitative researchers may increase the credibility of their research findings by drawing from evidence taken from a variety of data sources. 1.HIV infections. These are practices that we can adopt from scientific researchers and journalists. Triangulation In social science triangulation is defined as the mixing of data or methods so that diverse viewpoints or standpoints cast light upon a topic. 2003). You might, for example, use interviews and a focus group as different data sources … “Triangulation” is a term that is frequently mentioned in publications of qualitative studies. Attribution is the identification of the source of information. Triangulation of data means that data is drawn from different sources at different times, in different places, or from different people (possibly by using a different sampling technique). The points used to define the shape of the triangle (the corners, and sometimes a few more points) are called the "nodes". Typically, scholars mention “triangulation” in discussions to do with how the “quality” or “validity” of a study might be assured (e.g., Seale, 1999; Tracy, 2010). A Food for Thought webinarOne challenge of any higher education professional using and analyzing data is validating findings. Triangulation of data in qualitative research basically refer to drawing evidence from various data sources to study the same phenomenon. Triangulation in Assessment Whether conducting assessment FOR learning or assessment OF learning, a teacher must have sufficient proof of a students’ learning. Refer to Triangulation Matrix Format for more information on this data structure. The term triangulation refers to the practice of using multiple sources of data or multiple approaches to analyzing data to enhance the credibility of a research study. al. Each triangle is termed an "element". 4.Data analysis. The mixing of data types, known as data triangulation, is often thought to help in validating the claims that might arise from an initial pilot study. Triangulation facilitates validation of data through cross verification from more than two sources. Data sources: Possibly the most common way to Triangulation also has been viewed as a qualitative research strategy to test validity through the convergence of information from Use triangulation to create an in-memory representation of any 2-D or 3-D triangulation data that is in matrix format, such as the matrix output from the delaunay function or other software tools. Altrichter et al. Investigator triangulation means that different researchers (observers, interviewers, etc.) Data triangulation Investigator triangulation Theory triangulation Methodological triangulation Environmental triangulation 22. In computer vision triangulation refers to the process of determining a point in 3D space given its projections onto two, or more, images. Data Source Triangulation Data VISUALIZATION in EXCEL Prepared by: Ayva A. Mata’utia EXCEL User-Affordable friendly Readable Faster Tabulation 5 EXCEL DASHBOARD TIPS: HIGHLIGHT KEY DATA AT TOP MUTED COLOR WITH A FEW ACCENTS CLEAN AND SIMPLE LAYOUT Triangulation refers to the use of multiple methods or data sources in qualitative research to develop a comprehensive understanding of phenomena (Patton, 1999). The delaunay and delaunayn functions take a set of points and produce a triangulation in matrix format. The main sources of primary data used by Politics researchers are fourfold: The diagram to the right shows how different pieces of information can be put together to find a common area where data can be considered reliable (see Bakewell et. Using the delaunay and delaunayn functions. [… WHO Library Cataloguing-in-Publication Data HIV triangulation resource guide: synthesis of results from multiple data sources for evaluation and decision-making. These types of series provide built-in data triangulation that is automatically performed on items in the ItemsSource if no triangulation is set to the TrianglesSource property. Evaluating Information: Validity, Reliability, Accuracy, Triangulation 81 and data.3 Wherever possible, Politics researchers prefer to use primary, eye-witness data recorded at the time by participants or privileged observers. triangulation definition: 1. the division of a map or plan into triangles for measurement purposes, or the calculation of…. Each triangle is termed an "element". As data are drawn from multiple sources, it broadens the researcher's insight into the different issues underlying the phenomena being studied. Do not let the tri mislead you here – triangulation does not mean three! Involves using different sources of information in order to increase the validity of a study These sources are likely to be stakeholders in a program—participants, other researchers, program staff, other community members, and so on. Originating in navigational and surveying contexts, triangulation aligns multiple perspectives and leads to a more comprehensive understanding of the phenomenon of interest. Attribution and data triangulation are ways of evaluating information. 1 Describes the process by using multiple measures fora phenomena 2 Involves using different sources of information in order to increase validity of the study 3 Collecting data in the same way but using a variety of different times, participants and places. Data triangulation. Some consider triangulation as a method to substantiate findings and as a test for validity. (2008) contend that triangulation "gives a more detailed and balanced picture of the situation." In 2-D, the delaunay function is often used to produce a triangulation that can be used to plot a surface defined in terms of a set of scattered data points. "A convex hull algorithm and library for 2D, 3D, and higher dimensions. Margaret Zurieki -Triangulation is to gain good understanding from different perspectives of an investigated phenomenon by using multiple methods or data sources in qualitative research. Triangulation of data is what I most commonly see required of my clients. Triangulation involves using manifold data sources in an investigation to generate understanding, it can be primary or secondary data sources taken in place simultaneously. This notion is, however, controversial. In order to solve this problem it is necessary to know the parameters of the camera projection function from 3D to 2D for the cameras involved, in the simplest case represented by the camera matrices. … A Delaunay triangulation of a random set of 24 points in a plane. Triangulation in qualitative research has come to mean a multimethod approach to data collection and data analysis. The mesh is the collection of triangles. TRIANGULATION, a MATLAB library which computes a triangulation of a set of points in 2D, and carries out various other related operations on triangulations of order 3 or 6.. Triangulation also has been viewed as a qualitative research strategy to test validity through the convergence of information from different sources. The code can also be used to compute Delaunay triangulations and Voronoi meshes of the input data. 5.Qualitative research. According to O'Donoghue and Punch (2003), triangulation is a "method of cross-checking data from multiple sources to search for regularities in the research data." In this method, questions like “Is the source known?” or “Is the source credible and reputable?” are asked. The points used to define the shape of the triangle (the corners, and sometimes a few more points) are called the "nodes". 2.Data collection - utilization. When your data is represented using triangulation, you can perform topological and geometric queries, which you can use to develop geometric algorithms. Methodological triangulation can be used to enhance the analysis and the interpretation of findings. It tests the consistency of findings obtained through different instruments and increases the chance to control, or at least assess, some of the threats or multiple causes influencing our results. Different types of triangulation There are many ways of triangulating information. These types of series provide built-in data triangulation that is automatically performed on items in the ItemsSource if no triangulation is set to the TrianglesSource property. Assume that V is a finite point set on a two-dimensional real number field, edge e is a closed line segment composed of points in the point concentration as the end point, and E is a set of e. Then a triangulation T=(V,E) of the point set V is a plane graph G, which satisfies the conditions: The mesh is the collection of triangles. Multiple sources of data were used to create a triangulation of evidence: books, documentation, archival records and relevant publications by key actors, particularly in the development field, open ended interviews, participant-observation conducted during field work and a case study. The administrator of your personal data will be Threatpost, Inc., 500 Unicorn Park, Woburn, MA 01801. By using a process known as triangulation, teachers can obtain data of student learning from three different sources, thereby ensuring sufficient data is collected in order to evaluate student learning. Denzin (1978) and Patton (1999) identified four types of triangulation: (a) method triangulation, (b) investigator triangulation, (c) theory triangulation, and (d) data source triangulation. 3.Focus groups. In some triangulation examples, new sources of bias in some of the approaches might only become apparent once analysis begins. have been used to collect and interpret the data. Triangulation in this context simply means more than one. Learn more. TRIANGULATION, a C++ code which computes a triangulation of a set of points in 2D, and carries out various other related operations on triangulations of order 3 or 6.. The benchmarks indicate that the convex hull code and 4 and higher dimensional triangulation code is on par or better than the solution provided by the C++ library CGAL." source. Triangulation aims to integrate data from different methodological approaches with different biases and to exploit these differences to draw qualitative conclusions.
