Reliability and measurement validity are two key concepts in Research Methods. Provide one example of each to demonstrate your understanding of these terms and include in your post a YouTube video, article, or website that further advances your understanding of reliability and measurement validity.
Reliability additionally applies to individual measures. once folks take a vocabulary check twofold, their scores on the 2 occasions ought to be terribly similar. If so, the check will then be delineate as reliable. To be reliable, a listing activity vanity ought to offer identical result if given doubly to identical person at intervals a brief amount of your time. ratio tests shouldn't offer totally different results over time (as intelligence is assumed to be a stable characteristic).
