In case of mild depression, these therapies may be used as a stand-alone treatment. If you are suffering from severe depression, you should contact your psychiatrist and get immediate treatment" (Matthews, 2010, Editorial) Slide 10: Common sense example [Image: A large number 5] In your mind, rate the websites according to the 3 Cs Use a 1-5 scale Speaker's Notes: Overall, the Holistic Health website seems to be of average credibility, or a '5' on a scale of 1-10
In interpreting the reliability of results and work samples, a high level of coefficient alpha implies that numerous facets on the sample or results measure the same thing. It appears to be correlated and consistent (Bechet, 2008)
Psychological tests like attitudes and moods are factors expected to vary from one work sample to another during the intervals between tests and re-tests. In case of long durations during the intervals, attributes connected to achievement and ability would be expected to show up as results in the reliability of low-test retest (Heneman, Judge, & Kammeyer-Mueller, 2012)
1). Abundant research has been done on modern polygraph machines and techniques that has served to validate their use and their accuracy, however controversy still remains in the minds of many (Gougler et al
Finally, even if an employer is not 'caught,' flagrantly violating critical aspects of employee law, such as "overtime pay, family leave, final paychecks, or occupational safety and health," standards can have a negative impact upon employee morale and retention. (Guerin, 2006, p
Validity is simply the accuracy of a test to effectively measure the particular phenomenon that a researcher is attempting to measure. There are different types of validity including construct validity, content validity, and criterion-related validity (Richmond, 2013)
The assessment instrument I have selected is known as the HCR 20: Assessing Risk for Violence which is essentially a list of factors that have been determined to be related to future tendencies towards violence. The reliability of this instrument appears somewhat dubious, for the simple fact that many of the instructions for it -- including qualifications for individuals to administer it -- are decidedly vague (Webster et al
This process identified by the author as operationalization requires that the measures and their underlying construct have a close affinity. The closer the affinity the more valid the measure is (Kennedy, 1984)
The downside is that it is never easy to calculate reliability precisely. Ways of approximating it however, are in existence (Cherry, n

Examples are intelligence tests. Construct validity is therefore the extent to which a give instrument can measure a trait and/or a given theoretical construct that it is meant to measure (Miller et al
There is therefore a need for the researchers to carry out further investigations into the matter. Content validity Content validity refers to the degree to which the items in a given instrument are a reflection of the content universe for which a given instrument will be appropriately generalized (Straub et al
The test had nineteen items scored between 0 and 1, or 0 and 2, with a possible total score of thirty-three. Testing was stopped after four successive failures (Ripley and Yuill, 2005)
Problems / Pitfalls of a Reliability System: It's important for aircraft operators as well as engineering and reliability managers to identify the significance and impact of an aircraft's operational reliability and effectively address problems associated with it. Generally, there are several problems/pitfalls that are associated with an aircraft's reliability system including Complexity and High Costs: This is the major problem that the operators of an aircraft face since operational reliability of an aircraft is a design requirement that is complex and requires high costs of improvement for in-service aircraft (Bineid & Fielding, 2006)
However, new techniques were later developed that were focused on mechanical performance instead of the prediction of failure. The methods were jointly known as reliability control largely because of their major emphasis on maintaining failure rates below a particular fixed level (Khouzam, 2010)
¶ … reliability and validity in psychological testing. Why are reliability and validity important when choosing assessment instruments? In testing, reliability is another synonym for consistency "the degree to which an instrument measures the same way each time it is used under the same condition with the same subjects" or the "repeatability" of a measurement (Colosi 1997)
Or, they may try to simplify their psychological issues by ignoring the complexities of life. Subjects with low Lambda ratings tend to have few form-driven responses and show higher tolerance of ambiguity (Ganellen, 1996, p
If cost is the only issue addressed, problems are bound to eventually surface. RCM and Value Engineering Reliability Centered Maintenance (RCM) emphasizes the roles that reliability theory and practice assume in properly focusing preventive maintenance practices on retaining a product's design reliability (Brown, 1992)
Therefore, when used properly, value engineering is an excellent way to design parts, equipment and products in a way that provides the lowest cost without sacrificing reliability. Conclusion The Federal Acquisition Regulations defines value engineering as an organized effort to analyze the functions of systems, equipment, facilities, services, and supplies for the purpose of achieving essential functions at the lowest life-cycle cost consistent with required performance, quality, and safety (Heller, 1971)
Tim Smith, an engineer, said that, ideally, "value engineering is when a design is reviewed, and alternate means are suggested that result in the same system but at a lower cost. The value engineered system should perform the same as the original design while giving the owner the same value at a lower cost (Johnson, 2000)
