It is not enough for students to remember facts; they must be able to put the facts in the greater context of what the unit or course is designed to teach them. The Christian Science Monitor reported last year that American students lag behind their global counterparts in science and math (Paulson, 2010)
For instruments administered on the national level, however, it is much more difficult because our population is so diverse, both in terms of socioeconomics and racially, culturally and ethnically. Testing is supposed to be a learning experience that focuses on what students know (Petress, 2007, n
Conversely, the person who tends to elicit not so favorable reactions from others may be thought to have a 'bad' personality. However, when behavioral and social scientists seek to describe and define personality, the terminology used is far more rigorous that describing simple social skills (Cohen, Montague, Nathanson & Swerdlik, 1988)
Upon collection of the data, the researcher then calculates the correlations between every conceivable and possible pair of variables. In this way, the factor, in personality research is commonly viewed as a reflection of a personality trait (Gorusch, 1983)
If the result would be 0.00, then no relationship is indicated (Joint Committee, 1999)
The premise behind factor analysis suggests that if two or more characteristics correlate, they may reflect an underlying trait that is shared; thereby creating patterns of correlations that reveal the trait dimensions existing beneath the measure qualities (Tabachnik & Fidell, 2005). Factor analysis is a more complex version of correlation, however, in the sense that instead of examining correlation between just a few variables, factory analysis uses a great number of correlations among a great number of variables (Kline, 1994)
Factor Analysis in constructing Personality Testing Because there are so many ways in which to describe an individual's personality, those interested in personality frequently use a statistical tool to simplify the enormous amounts of information available by placing similar information into clusters known as factor analysis. The premise behind factor analysis suggests that if two or more characteristics correlate, they may reflect an underlying trait that is shared; thereby creating patterns of correlations that reveal the trait dimensions existing beneath the measure qualities (Tabachnik & Fidell, 2005)
Through the representation of some truly catastrophic failures, this video graphically and clearly illustrates the importance of quality. Accelerated Life Testing refers to efforts to test products and other outputs in a manner that reflects the use and wear they are expected to receive during their life cycle in the hands of consumers, but at an accelerated pace that allows a company to find problems and/or means of enhancing the product/output's performance without needing to wait the often long periods of time (years, for a large number of consumer products) that a true product life cycle would take (Bagdonavi-ius & Nikulin, 2002)
And since it would be difficult to determine whether indeed, a source is credible -- in fact, the concept of credibility is difficult to conceptualize and qualify -- triangulation is the best tool to use to test for validity and reliability in qualitative data. In triangulation, analysis of data/information from qualitative methods are triangulated by verifying it against quantitative research findings of similar topic or issue, whether this quantitative study is done in parallel to the qualitative study or not (Golafshani, 2003:603)
the construct being measured." Lastly, construct validity ensures that the construct measured in the study is accurately defined and the definition is mutually exclusive for that concept only (Smith, 1988:48)
Number of individuals spending time in homeless shelters (nominal): "Roughly 170,000 families spent at least one night in a shelter in 2009" according to the Department of Housing and Urban Development. While reliable statistics on homelessness can be difficult to obtain, the number of individuals who seek refuge in shelters is one indication of the extent of the problem (Morales 2010) 7
Reliability When one is discussing experimental results, two terms become very important: validity and reliability. Validity refers to "the extent to which a test measures what it claims to measure" (Cherry, 2011, Validity)
Reliability When one is discussing experimental results, two terms become very important: validity and reliability. Validity refers to "the extent to which a test measures what it claims to measure" (Cherry, 2011, Validity)
The test should measure the candidate against established precursors for university success. Such factors can include personality traits such as leadership, creativity and resiliency (Tomsho, 2009)
Each year thousands of people die taking part in high risk behaviors but their deaths do nothing to slow others from following in their footsteps. In addition to taking part in high risk behaviors for fun, people often do so because they are in a hurry (Lanoie, 1992)
Ergonomics often is described as matching human capabilities (physical, psychological, physiological and biomechanical) to the demands of a specific task. When there is a mismatch in some of these requirements, one of the consequences may be the development of musculoskeletal injuries (Ware, 2005)
One of the ways that a safety culture is promoted is through the use of employee training. Employees are provided training not only for positions that involve lifting and driving but also for administrative work with regard to desk heights, computer screen locations and other aspects of employment (Wolff, 1999)
The experiences of several other food retailers and their strategies for preventing workplace accidents are presented. The battle to reduce workplace injuries has long been waged on many fronts - from meticulous floor maintenance programs that prevent slips and falls to the enforcement of case weight limits to avoid back injuries caused by excessive lifting (Zimmerman, 1995)
Slide 4: Obey the Three Cs': Credibility, Compatibility And Common Sense Speaker's Notes: When evaluating an alternative health website or other source of information, apply the 'Three Cs': Credibility, Compatibility, and Common Sense Slide 5: Credibility Is the website credible? What are the author's credentials? Speaker's Notes: Is the website credible? Ask yourself: Who authored this website? What are the author's credentials? If the author is a layperson, remember that one person's anecdotal experience does not have the weight of a scientific study, and correlation between a single person's alleged recovery and a particular treatment does not equal causation. Also there is the issue of bias -- is the website author selling a particular kind of supplement or treatment? If they have legitimate credentials, do they back up their claims with footnotes, links to legitimate resources such as the National Institute of Health (NIH) and the Journal of American Medicine) or websites of professional associations such as the American Medical Association? (Benedetti, 2010) Broken 'links,' grammatical and spelling errors, strange fonts in odd colors, and exclamation points, are obvious red flags
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
