Reliability

2.2. Concept of Madhab’s Hat curve of Reliability By using the above data, Mean Time Between Failures and the Reliability for each year has been calculated as shown in the Table 2. As explained earlier the reliability has been calculated by using failure data method. Like Bath Tub curve we can put the data of Reliability for all the years in MINITAB software and after putting the data we got a curve which is shown in the figure - 3. If we observe closely we can mark the curve looks lika a Hat.…

Introduction: It is human nature to constantly strive for improvements in what we do and how we do things on a daily basis (Carling, et al., 2005). Soccer is no different, and many coaches are constantly looking for ways to improve their team’s performance. According to Hughes, et al. (2012) team invasion sports such as soccer provide an ideal field for analysis as they consist of a combination of individual techniques set within a team framework. Carling, et al. (2005) states correct analysis…

Postert, Beyer, Furniss, & Achtergarde, 2010). It is essential professionals are aware of the reliability and validity of an instrument when being employed. Reliability and Validity of The Symptoms Checklist…

measurement can be regarded as reliable if gives a consistent result. According to Bryman (2004), the three outstanding means of measuring reliability are: test- retest reliability which involves testing and administering same test to the same respondent on different occasions to check the reliability of the result. Alternate form reliability is another feature of reliability which applies to differently worded items for measuring the same variable. Jupp (2006) also called this the “split half…

for test takers ages 7-17 either in the educational or clinical setting to evaluation depression symptoms. Lee, Krishnan, and Park (2011; 2012) discusses the psychometric properties of the test to help address the question of the specific type of reliability, the associated source of error, as well as Lee, Krishnan, and Park’s interpretation of the results. The study presented by Lee, Krishnan, and Parks (2011; 2012) used the Item Response Theory approach to investigate the psychometric…

in his work of 1989 that whilst soldiers value total war, it leaves home fronts in a state of economic and social calamity. The origin aids in reliability, as the date of 1988 was post-war, and thus was no censorship on what historians wrote, meaning Kennedy’s descriptions are free of external control. The narrow perspective Kennedy limits the reliability, evident in his favorable comparisons of the allied home fronts, opposed to the German home front. The sources fails to consider the positive…

Interviews will be the primary means to collect the data for this study. Each participant will be interviewed based on an interview guide (see Appendix B: Interview Guide). Because of the complexity of meeting the participant more than once semi-structured interviews will be the most convenient to collect the data (Doody & Noonan, 2013). Semi-structured interviews will help the researcher to develop a keen understanding of the experience of the undocumented immigrants. The interviews will…

from 0.689 to 0.827. It appears to be useful and contributes to the overall reliability of TRU. Hence, after screening, the measurement items in TRU are still maintained from 4 to 3 items: TRUi (i=1, 2, 4) and the correlation among these items is rather high (0.676; 0.715 and 0.664, respectively). It indicates that there is a positive correlation between one item and the rest of TRU (see in Table…

practices Maintenance activities are defined as the set of activities aimed at improving the overall reli-ability and availability of an equipment (Kamran, 2003). Maintenance practices are defined as the set of activities that enhance the equipment reliability and availability at the minimum cost of production to achieve market competitiveness (Alsyouf, 2007). Maintenance practices are defined as activities which are concerned with preventing or responding to failure and opti-mization of the…

Assessment tools have evolved to test these different components and the format of final examinations at the end of undergraduate and postgraduate medical training has shown significant change over the past forty years, all in an attempt to improve the reliability and validity of the process. The patient is increasingly more aware and demanding of what is expected of a doctor – to diagnose and treat his condition whilst maintaining a certain…
