Document Summary

Reliability is often associated with being dependable, accurate, honest, trustworthy, consistent, etc. Is defined in research as the accuracy that a measure has in producing stable, consistent measurements. Refers to the reliability of individual research scales. Almost every quantitative research study employs at least one research scale; It is necessary to find a way to determine whether people are consistently filling out the scale. If you have two questions (i like public speaking and i dislike public speaking) on a likert scale with five steps running from 1 to 5 (strongly disagree - strongly agree) Consistent participant would score 5 one the first and 1 on the second. If they score 1 one on both there is an issue. Method for testing the reliability of an instrument is to measure the same thing on more than one occasion and see whether you get the same score.
