Reliability and validity are concepts used to evaluate the quality of research. They indicate how well a method, technique or test measures something. Reliability is about the consistency of a measure, and validity is about the accuracy of a measure.

What is an example of reliability and validity?
A simple example of validity and reliability is an alarm clock that rings at 7:00 each morning, but is set for 6:30. It is very reliable (it consistently rings the same time each day), but is not valid (it is not ringing at the desired time).
What is validity and reliability in research examples?
For a test to be reliable, it also needs to be valid. For example, if your scale is off by 5 lbs, it reads your weight every day with an excess of 5lbs. The scale is reliable because it consistently reports the same weight every day, but it is not valid because it adds 5lbs to your true weight.
What is validity of a test?
Test validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure.
How do you measure validity and reliability?
Reliability is assessed by one of four methods: retest, alternative-form test, split-halves test, or internal consistency test. Validity is measuring what is intended to be measured. Valid measures are those with low nonrandom (systematic) errors.
