How do researchers determine reliability in a study?
There are two distinct criteria by which researchers evaluate their measures: reliability and validity.
Reliability is consistency across time (test-retest reliability), across items (internal consistency), and across researchers (interrater reliability)..
What is reliability in research?
In simple terms, research reliability is the degree to which research method produces stable and consistent results. A specific measure is considered to be reliable if its application on the same object of measurement number of times produces the same results.
How do you know if research is reliable?

What is Reliability example?

What will happen if there is no research in our society?
We would become unaware, trapped in inanity. We would not move forward, be exposed to better ways of doing things. We would be born with curiosity, live with curiosity and die with curiosity.
