What is reliability, accuracy and validity? (1 Viewer)

Well - self explanatory question. I'm well aware that I can Google it, but, I'm wondering if there are any different perspectives out there.

reliablity - source or answer is trustworthy based on consistency of results
accuracy - how precise your answer is based on ur number of trials
validity - ? LOL

My reliability and accuracy sound the same

Accurate - how close the something is
Reliability - how believable or trustworhy something is
Validity - how truthful something is

accuracy is the percentage difference between the experimental result and accpeted value

reliability is the repeatability, consistency, trustworthiness and how much you can depend upon results

validity is how fairly the experiment tests the hypothesis, if the results are derived correctly from premises already accepted and supported by actual fact than the experiment is valid

Compared with your definitions, my definitions are quite pathetic.

Thank you Without Wings. I've used Bob Emery's site for the past term and a bit for practicals. But I have prac exams tomorrow, and in true procrastination style, I've wondered if there's any aspect of accuracy, validity and/or reliability that I've left out.
