Test-Retest Reliability

Values and Motives Questionnaire: The Technical Manual (n.d.). Retrieved from the Liberty COUN 521 website: Psytech International.

The Values and Motives Questionnaire, also known as the Values and Motives Inventory, is designed to examine a person’s motivation in relation to his values and activities. In order to ensure a comprehensive understanding of values, the VMQ assess three distinct areas, including: interpersonal, intrinsic, and extrinsic. Interpersonal values, according to the VMQ refer to one’s relationships with others. Intrinsic values contain one’s personal beliefs and attitudes. Finally, extrinsic values are one’s motivating factors at the workplace. Each of these three areas contain twelve topics

Memory span is a measure of short term memory and its capacity through the use of a list. Participants are asked to review a list of items, retain, and immediately recall as accurate as possible. The list may be conducted with a random list of numbers, words, or letters since these items may influence differently amongst each participant. The list is also varied in item length to test in which particular length the participant is subject to make the least of errors and determine their memory span. The average short-term memory capacity is ranged

Reliability generalization examines reliability of scores from tests and detect the causes of measurement error (Kline, 2005).

The reliability of an assessment in a perfect situation should produce the same results if marked by another tutor or if that examiner unknowingly receives the same paper again. If different marks are given the assessment is consequently unreliable and proves that this assessment is subjective.

The Protein power diet was first introduced to the public around the year of 1996 by two MD family doctors DR. Michael Eades and DR. Mary Eades. The protein power diet is based on the idea that controlling the level on insulin that will help you regulate the blood pressure, cholesterol, triglycerides, and fat storage in the. The protein power is a high protein, low-carbohydrate diet. This type of diet is mainly based on about 30 to 60 grams of carbohydrates and lots of lean proteins. This diet is very easy to follow and gives great fast result in no time, keeping your body lean. Protein serves primarily to promote growth and maintenance of the body tissue, it is also a primary component of enzyme and hormone

The author Joelle Charbonneau wrote the book The Testing. An amusing fact about Joelle is that she taught many students how to sing. In an article Joelle states “My students are a wonderful source of inspiration and continue to teach me life while I teach them about singing” (Charbonneau… New York Times). The Testing by Joelle Charbonneau is about a girl named Cia who is selected to go through a testing program to test her knowledge and see if she can attend a certain college. Cia has many roadblocks, but that does not stop her from doing her best. People should recommend this book because of its connection to the article titled New Surveillance Technology. The message of this book is that knowledge is power, so don’t betray it.

Evaluating human services is a task that can be very complex. People can have different interpretations of the same event. Another concern is that people are not always honest. Therefore, human services will gain from effective, high quality evaluations of data collection methods. This requires that the data collection methods supply accurate and dependable information. This paper will define and describe 2 concepts of measurement known as reliability and validity,-provide examples and supporting facts as to how these concepts apply to data collection in human services, and evaluate the importance of the validity and

Memory retrieval is likely to be good after repeated testing of that material. In fact, practising retrieval has a larger effect on memory than revising the information (Hockley, 2009).

The results found that when retested at a later date, the participants who were tested, did far better than those who were only tested once. For the final test after all sets, the group that was consistently tested got

The manual discusses internal consistency and test-retest in terms of reliability. Internal consistency is measuring how scores on individual items relate to each other or to the test as a whole. In two subsample studies, high internal consistency was found. In the first study, with a mixed sample of 160 outpatients, Beck, Epstein et al. (1988) reported that the BAI had high internal consistency reliability (Cronbach coefficient alpha = .92), and Fydrich et al. found a slightly higher level of internal consistency (coefficient alpha = .94). This means that the items on the BAI are all measuring the same variable, anxiety.

When thinking of reliability let us assume there is kitchen scale if one weigh 5 pound of oranges and the scale is reliable. Likewise the scale register 5 pound of oranges hours later. The assessment should not make any the different whether the assessment was taken in the morning or afternoon. Though, reliability is not a characteristic of a test or other instrument. (McMillan, 2012). “But the “reliability of score was adequate (McMillan,

Internal consistency--The application and appropriateness of internal consistency would be viewed as reliability. Internal consistency describes the continuous results provided in any given test. It guarantees that a range of items measure the singular method giving consistent scores. The appropriateness would be to use the re-test method in which the same test is given to be able to compare whether the internal consistency has done its job (Cohen & Swerdlik, 2010). For example a test that could be given is the proficiency test which provides three different parts to the test, but if a person does not pass the test the same test is given again.

Reliability is defined, within psychometric testing, as the stability of a research study or measure(s). Reliability can be examined externally, Inter-rater and Test-Retest, as well as internally; which is seen in internal consistency reliability methods.
