Triangulation (social science)

From Wikipedia, the free encyclopedia
For other uses of triangulation, see Triangulation (disambiguation).

In the social sciences, triangulation is often used to indicate that two (or more) methods are used in a study in order to check the results. "The concept of triangulation is borrowed from navigational and land surveying techniques that determine a single point in space with the convergence of measurements taken from two other distinct points."[1] The idea is that one can be more confident with a result if different methods lead to the same result.

Triangulation is a powerful technique that facilitates validation of data through cross verification from two or more sources. In particular, it refers to the application and combination of several research methodologies in the study of the same phenomenon.[2]

  • It can be employed in both quantitative (validation) and qualitative (inquiry) studies.
  • It is a method-appropriate strategy of founding the credibility of qualitative analyses.
  • It becomes an alternative to traditional criteria like reliability and validity.
  • It is the preferred line in the social sciences.

By combining multiple observers, theories, methods, and empirical materials, researchers can hope to overcome the weakness or intrinsic biases and the problems that come from single method, single-observer and single-theory studies.

Purpose

The purpose of triangulation in qualitative research is to increase the credibility and validity of the results. Several scholars have aimed to define triangulation throughout the years.

  • Cohen and Manion (2000) define triangulation as an "attempt to map out, or explain more fully, the richness and complexity of human behavior by studying it from more than one standpoint."[3]
  • Altrichter et al. (2008) contend that triangulation "gives a more detailed and balanced picture of the situation." [4]
  • 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."[5]
  • According to Erina Audrey (2013) “Triangulation also crosschecks information to produce accurate results for certainty in data collection”

Types

Denzin (1978) identified four basic types of triangulation:[6]

  • Data triangulation: involves time, space, and persons
  • Investigator triangulation: involves multiple researchers in an investigation
  • Theory triangulation: involves using more than one theoretical scheme in the interpretation of the phenomenon
  • Methodological triangulation: involves using more than one method to gather data, such as interviews, observations, questionnaires, and documents.
