Why are 3 stations needed to locate an epicenter?
Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Knowing this helps them calculate the distance from the epicenter to each seismograph.
How many days Mcgrath stations are needed to locate the epicenter of an earthquake?
three seismographs
Which earthquake wave is most destructive?
During an earthquake, surface waves are the seismic waves that cause the most damage. Unlike other seismic waves that move deep inside the Earth, surface waves move along just under the surface of the Earth like waves in water.
What is emotional triangulation?
Triangulation occurs when an outside person intervenes or is drawn into a conflicted or stressful relationship in an attempt to ease tension and facilitate communication. This situation is often seen in family therapy.
What is an example of data triangulation?
Data triangulation involves the use of heterogeneous data sources, for example, qualitative and quantitative. Alternatively data may be gathered (using the same method) from different sources or at different times, for example, the pre-‐ and post-‐use of a questionnaire.
What is triangulation narcissist?
In the context of narcissism, triangulation occurs when the narcissist attempts to control the flow, interpretation, and nuances of communication between two separate actors or groups of actors. Ensuring communications flow through, and constantly relate back to the narcissist provides a feeling of importance.
What do you mean by data triangulation?
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. First, data triangulation involves using multiple sources of data in an investigation.
What is the purpose of triangulation?
Triangulation facilitates validation of data through cross verification from more than two sources. 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.
What is the triangulation method and when is it necessary?
Triangulation is a method used to increase the credibility and validity of research findings. 2 Triangulation, by combining theories, methods or observers in a research study, can help ensure that fundamental biases arising from the use of a single method or a single observer are overcome.
Is member checking a form of triangulation?
Multiple data collection methods and member checking are appropriate methods to adopt within a subtle realist approach, enabling a triangulation of knowledge about a single phenomenon. Methods from different paradigms can be used, or data collected from different sources, at different times (Torrance, 2012).
How is member checking done?
Member checking, also known as participant or respondent validation, is a technique for exploring the credibility of results. Data or results are returned to participants to check for accuracy and resonance with their experiences.
What is the difference between member checking and transcript review?
What is the difference between member checking and transcript review? Transcript review is when a qualitative researcher sends a copy of the interview transcript to each respective participant so they can review the document. Member checking is often mentioned as one in a list of validation techniques.
What are member reflections?
Braun and Clarke described member reflection as an approach that does not focus on participants’ validation of research findings; instead it can be considered as ‘an opportunity for “reflexive elaboration” of the results rather than testing whether the researcher has “got it right”’ (Braun and Clarke 2013.
Why do qualitative researchers include member checking in data analysis?
Why do qualitative researchers include “member checking” in data analysis? A Member checking ensures validation of data, not continued participation.
