What is the meaning of reliability and validity?

Reliability and validity are both about how well a method measures something: Reliability refers to the consistency of a measure (whether the results can be reproduced under the same conditions). Validity refers to the accuracy of a measure (whether the results really do represent what they are supposed to measure).

How do you determine reliability?

How to measure it. To measure interrater reliability, different researchers conduct the same measurement or observation on the same sample. Then you calculate the correlation between their different sets of results. If all the researchers give similar ratings, the test has high interrater reliability.

Why is it important to know the reliability of a test quizlet?

High inter-rater reliability is important because it increases confidence that the procedure is really measuring what it is supposed to measure.

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.

What is reliability in qualitative research?

Reliability in qualitative research refers to the stability of responses to multiple coders of data sets. It can be enhanced by detailed field notes by using recording devices and by transcribing the digital files. However, validity in qualitative research might have different terms than in quantitative research.
