Reliability and Validity Ebony Johnson University of Phoenix Reliability has to do with the quality of measurement and is the consistency of repeatability of measures. To define it precisely researchers first have to learn about the foundation of reliability- the true score theory of measurement. Then researchers need to understand the different types of measurement error because they play a key role in degrading reliability. Because reliability can only be estimated there are different types

have similarities in their tissues and DNA. Though parts of the human body vs. an animal’s body may have similarities but people must keep in mind that we are two totally different species. Science shows that animals rarely serve as good models for the human body so why would we feel safe with the product anyways. The best thing for us to do is test out products on other humans so then we can get reliable and accurate results. The Food and Drug Administration (FDA) stated that 92% of all drugs that

survey needed to demonstrate validity and reliability. Validity‚ as described by Heale and Twycross (2015‚ 66)‚ examines whether the specific concept has been accurately measured. In contrast‚ according to Floss (2013‚1)‚ reliability refers to the consistency of the instrument to measure the concept. The instrument needed to feature external validity in order for the data collected to be generalised (Heale and Twycross 2015‚ 66). To ensure the instrument was reliable‚ the questions featured limited

Freud’s definition of conscience is linked to an individual’s
