How do you know if a study is reliable?
Reliability can be estimated by comparing different versions of the same measurement. Validity is harder to assess, but it can be estimated by comparing the results to other relevant data or theory. Methods of estimating reliability and validity are usually split up into different types.
What is the key concept of validity?
Validity refers to how accurately a method measures what it is intended to measure. If research has high validity, that means it produces results that correspond to real properties, characteristics, and variations in the physical or social world.

Which is the best description of Trochim research methods?
Trochim, Research Methods Knowledge Base. Trochim (2006) champions qualitative research as a method to develop new ideas and study phenomena in great detail and understanding. As a tradeoff, qualitative research is not generalizable as opposed to experimental studies, and qualitative research finds much greater difficulty receiving funding.
What is the definition of credibility in Trochim?
Trochim instead lists a number of similar concepts: credibility, transferability, dependability, and reliability. Interestingly, credibility is a measurement from the subjects’ perspective on whether research outcomes are believable.
When do we think about validity in research?
The first thing we have to ask is: “validity of what?” When we think about validity in research, most of us think about research components. We might say that a measure is a valid one, or that a valid sample was drawn, or that the design had strong validity. But all of those statements are technically incorrect.
When do we use the four validity types?
Because all four validity types are really only operative when studying causal questions, we will use a causal study to set the context. The figure shows that there are really two realms that are involved in research.
