Reliability engineering

refers to a tool implemented in analytical psychology. Just like any other scientific tool, criminal profiling has its disadvantages. The disadvantages influence the validity, reliability, and utility of the technique, making it to be classified as a tool rather than science. For one to be conversant with the validity, reliability, and usefulness of this tool, understanding its definition is crucial. Criminal profiling refers to the procedure of categorizing personality mannerisms, behavior…

Test Design and Evaluation Participants Two groups of participants will be recruited; a control group consisting of healthy American soldiers and an experimental group consisting of American soldiers who sustain a concussion. Participation will be voluntary and participants should be free of any history of concussion or cognitive impairment. Due to the disproportionate gender representation of soldiers only men will be included and participants have to be between 18-50 years. The study will…

Concept of a Leader There are many definitions of leadership. The Collins English dictionary defines leadership as “the leader of a party or group.” Yet true leadership is much more than that. A decent leader has an excellent character. It is of most extreme significance that a pioneer is reliable to lead others. A pioneer should be trusted and be known to carry on with their existence with genuineness and respectability. A decent leader has a superb character. It is of most outrageous…

Story evaluation The story that will be evaluated is one entitled “Man was paid $2 500 to conceive a child with his neighbor’s beauty queen wife, but failed after 3 months trying”. Firstly, there is doubt in the story due to the source which is responsible for sharing the news. The source is a website known as 9GAG, which does not have any reputable evaluation system, and anyone is free to post a story he or she wants. However, judging by the comments on the post, many individuals assume the…

Reliability and Validity Reliability refers to the extent to which a series of similar assessments are consistent in the result they give (Rubin & Babbie, 2010). This is a crucial aspect of carrying out tests which may be a way of testing bias as well as distortion. For instance, this can be tested in an actual situation with a DNA test. A DNA test that needs to show if a suspects DNA matches a sample at a crime scene. To ensure that the scale is reliable, the sample can be tested twice and if…

these two schools of thought have produced much articles, books and researchers in parallel. Therefore, while the researchers belonging to HRO were busy in assessing aircraft carriers, air traffic controls and nuclear power plants, the Resilience Engineering researchers were developing conceptualization of problem of error and its eventual consequences for interfaces design in nuclear, aviation and medicine aspects. In early 90s, HROs in relation to the thesis of a normal accident debated the…

tests would score higher on lower level of the same test. To answer this question much of the research on out-of-level testing has examined the effects on raw scored and derived scores. Many have turned to chance score as a criterion measure of reliability. When the effects of the out-of-level testing on chance scores have been examined, researchers found that the number of students who score at the chance level on a…

The two assessments that were administered to the client were the Gambler Addiction Index (GAI) and the Coping Response Inventory Adult Form (CRI). The purpose of the GAI is to measure the severity and intensity of an individual’s gambling addiction. In addition to, the assessment measures the strong impulses an individual has to gamble and the harmful consequences of gambling. The rationale of selecting this assessment for the client, Alan, was because in the previous session, Alan mentioned an…

assessed by experts and made sure the scales were correct. In the development of the Japanese version there was special attention put on the differences between North American and Japanese cultural difference. Results showed high internal consistency reliability with a Cronbach’s alpha of .87 and the mean inter-item correlation of .24 (Kojima et al., 2002). Factorial validity was proven by conduction a factor analysis and the researchers found “an almost identical pattern matrix with the…

However, negatively scored items were used sparingly (see Appendix B). Validity and Reliability An instrument is valid when it measures the construct it was designed for, and reliable when an instrument can consistently produce the same results over time, across different situations (Field, 2003). Content validity is an evaluation of the…
