AdministratorWhat is trustworthiness research?
Trustworthiness is defined as the believability of the researcher’s findings, i.e. all that the researcher has done in designing, carrying out and reporting the research to make the results credible.
What is Rigour in quantitative research?
Rigour refers to the extent to. which the researchers worked to enhance the quality of. the studies. In quantitative research, this is achieved. through measurement of the validity and reliability.1.
What is validity and reliability in quantitative research?
Validity is defined as the extent to which a concept is accurately measured in a quantitative study. The second measure of quality in a quantitative study is reliability, or the accuracy of an instrument. …
What are the characteristics of reliability?
The basic reliability characteristics are explained: time to failure, probability of failure and of failure-free operation, repairable and unrepairable objects. Mean time to repair and between repairs, coefficient of availability and unavailability, failure rate. Examples for better understanding are included.
What is the most common test for internal consistency?
Cronbach’s alpha: The most commonly used measurement of internal consistency. Split-halves test: Involves splitting the test items in half (i.e., forming a group of all even items and another group with all of the odd items) and correlating the two halves. Kuder-Richardson test: Similar to the split-halves test.
What makes you a reliable person?
What is a reliable person? A reliable person is someone who keeps their word. It’s someone that when they say that they will do something, they are doing it, no questions asked. It’s someone that we can count on because they always did what they said they would and they never let you down.
Why is external reliability important?
External reliability This assesses consistency when different measures of the same thing are compared, i.e. does one measure match up against other measures? Discrepancies will consequently lower inter-observer reliability, e.g. results could change if one researcher conducts an interview differently to another.
What is external reliability?
the extent to which a measure is consistent when assessed over time or across different individuals.
What is the purpose of trustworthiness in qualitative research?
The aim of trustworthiness in a qualitative inquiry is to support the argument that the inquiry’s findings are “worth paying attention to” (Lincoln & Guba, 1985). This is especially important when using inductive content analysis as categories are created from the raw data without a theory-based categorization matrix.
Why is internal consistency important?
Internal consistency reliability is important when researchers want to ensure that they have included a sufficient number of items to capture the concept adequately. If the concept is narrow, then just a few items might be sufficient.
What is credibility in quantitative research?
Credibility refers to the extent to which a research account is believable and appropriate, with particular reference to the level of agreement between participants and the researcher. The notion of credibility is most often associated with the framework presented by Yvonna Lincoln and Egon Guba.
What is external validity in psychology?
External validity is the extent to which you can generalize the findings of a study to other situations, people, settings and measures. Without high external validity, you cannot apply results from the laboratory to other people or the real world.
What is the importance of reliability?
Reliability is a very important piece of validity evidence. A test score could have high reliability and be valid for one purpose, but not for another purpose. An example often used for reliability and validity is that of weighing oneself on a scale.
