For example, given a series system of two components with different reliabilities — one of 0.95 and the other of 0.8 — Lusser's law will predict a reliability of :R_s = 0.95 \times 0.8 = 0.76 which is lower than either of the individual components.

The Korean MMPI-2 was initially translated by Kyunghee Han through a process of multiple rounds of translation (English to Korean) and back-translation (Korean to English), and it was tested in a sample of 726 Korean college students. In general, the test-retest reliabilities in the Korean sample were comparable to those in the American sample. For both culture samples, the median test-retest reliabilities were found to be higher for females than for males: 0.75 for Korean males and 0.78 for American males, whereas it was 0.85 for Korean females and 0.81 for American females. After retranslating and revising the items with minor translation accuracy problems, the final version of the Korean MMPI-2 was published in 2005.

97 for Spelling II. During the norming study, both levels of the WRAT were administered to children ages 9 through 14. Since there is overlap in skills tested between the high end of level I and the low end of level II, this provides another estimate of the reliability of both. On Reading and Spelling, split-half reliabilities ranged from .88 to .

The results produce several different scores including total recall, learning strategy, serial position effect, learning rate, consistency of item recall, proactive and retroactive interference, and retention over long and short delays. Internal consistency and alpha reliabilities for the test are high (usually >0.80).Mottram, L., & Donders, J. (2005).

The PANAS-SF, comprises 10 items that were determined through the highest factor loadings on the exploratory factor analysis reported by Watson et al. (1988) in his original PANAS. Previous mood scales, such that of Bradburn, had low reliabilities and high correlations between subscales. Watson was able to address these concerns in his study of the original PANAS; however, his participants consisted mostly of student populations.

These newly developed missiles were made available to civilians of NASA for various projects (which would have the added benefit of demonstrating the payload, guidance accuracy and reliabilities of U.S. ICBMs to the Soviets). While NASA stressed peaceful and scientific uses for these rockets, their use in various lunar exploration efforts also had secondary goal of realistic, goal-oriented testing of the missiles themselves and development of associated infrastructure, just as the Soviets were doing with their R-7.

Eight years after their original construction of the SAS, the researchers developed a revised version (the SAS II) to improve its reliability. The earlier reliabilities of Social complexity and Fate control were lower than they liked, and they hoped to generally improve its performance between cultures.Leung, Kwok; Lam, Ben C. P.; Bond, Michael Harris; Conway, Lucian Gideon III; Gornick, Laura Janelle; Amponsah, Benjamin; Boehnke, Klaus; Dragolov, Georgi; et. al. (2012).

According to the Benton Test manual, test- retest reliability of the Benton Test is 0.85, and alternate form reliabilities range from 0.79 to 0.84. Correlation between immediate and delayed memory recall (Administration type A and D, respectively) ranges from 0.40 to 0.83, depending on the combinations of forms used. Included with the manual are standardized results for children, adolescents, and adults, though each administration method have their own standardization data. Total errors on the test have been shown to increase with age, especially after the age of 70.

However, the psychometric properties of Saucier's original mini-markers have been found to be suboptimal with samples outside of North America. As a result, a systematically revised measure was developed to have better psychometric properties, the International English Mini-Markers. The International English Mini-Markers has good internal consistency reliabilities, and other validity, for assessing extraversion-introversion and other five-factor personality dimensions, both within and, especially, without American populations. Internal consistency reliability of the extraversion measure for native English-speakers is reported as a Cronbach's alpha (α) of 0.92, that for non-native English- speakers is α of 0.85.

The Maritime Electronic Warfare Systems Division models a systems engineering sustainment system that automates Electronic Warfare (EW) Systems sustainment activities. The model is created using the IBM Rational Rhapsody tool using the SysML modeling language and DoD Application Framework (DoDAF). The sustainment model implements life-cycle activities including logistics delays based on real or proposed replacement part reliabilities, quantities, and locations, along with workflows and processes to support a performance-based sustainment (PBS) solution for Electronic Warfare Systems. Using SysML and DoDAF, the interactions between Crane employees, automated tools, the Electronic Warfare systems, and data to accomplish PBS are simulated.

Words representing disagreeableness are reverse coded. Goldberg (1992) developed a 20-word measure as part of his 100-word Big Five markers, and Saucier (1994) developed a briefer 8-word measure as part of his 40-word mini-markers. Thompson (2008) systematically revised and improved these markers to develop a 40-word measure with better psychometric properties in both American and non- American populations, the International English Mini-Markers. This brief measure has good internal consistency reliabilities and other validity for assessing agreeableness and other five factor personality dimensions, both within and, especially, without American populations.

Compared to the U. S. norm, scale means of Korean norm were significantly elevated; however, the reliabilities and validity of the Korean MMPI-2 were still found to be comparable with the English MMPI-2. The Korean MMPI-2 was further validated by using a Korean psychiatric sample from inpatient and outpatient facilities of Samsung National Hospital in Seoul. The internal consistency of the MMPI-2 scales for the psychiatric sample was comparable to the results obtained from the normative samples. Robust validity of the Korean MMPI-2 scales was evidenced by correlations with the SCL-90-R scales, behavioral correlates, and therapist ratings.

There are few recognised measures of quality of working life, and of those that exist, few have evidence of validity and reliability, although the Brief Index of Affective Job Satisfaction has been systematically developed to be reliable and is rigorously psychometrically validated. The Brief Index of Affective Job Satisfaction (BIAFJS) is a 4-item, purely affective as opposed to cognitive, measure of overall affective job satisfaction that reflects quality of working life. The BIAJS differs from other job satisfaction measures in being comprehensively validated not just for internal consistency reliability, temporal stability, convergent and criterion-related validities, but also for cross-population invariance by nationality, job level, and job type. Reported internal consistency reliabilities range between .

The Occupational Analysis Inventory (OAI) contains 617 "work elements." It was designed to yield more specific job information than other multi-job questionnaires such as the PAQ while still capturing work requirements for virtually all occupations. The major categories of items are five-fold: # Information Received # Mental Activities # Work Behavior # Work Goals # Work Context OAI respondents rate each job element on one of four rating scales: part-of-job, extent, applicability, or a special scale designed for the element. The OAI has been used to gather information on 1,400 jobs selected to represent five major occupational categories. Reliabilities obtained with the OAI have been moderate, somewhat lower than those achieved with the PAQ”.

The original scale to measure the effects of various substitutes was developed by Kerr and Jermier (1978). They assessed leadership substitutes via a questionnaire that contained thirteen subscales with a total of 55 items. The items were on a Likert scale ranging from 1 (almost always untrue or completely untrue), to 5 (almost always true or almost completely true). The subscales included were: # Ability, experience, training, and knowledge # Professional orientation # Indifference towards organizational rewards # Unambiguous, routine, and methodically invariant tasks # Task-provided feedback concerning accomplishment # Intrinsically satisfying tasks # Organizational formulization # Organizational inflexibility # Advisory and staff functions # Close-knit, cohesive, interdependent work groups # Organizational rewards not within the leader's control # Spatial distance between superior and subordinates # Subordinate need for independence Kerr and Jermier (1978) tested nine of these subscales in a lab setting and found that they were independent and had adequate internal reliabilities.

Strategies have been developed which lead SRAM PUF to become more reliable over time without degrading the other PUF quality measures such as security and efficiency.Maes, R, and Van der Leest, V. "Countering the effects of silicon aging on SRAM PUFs", Proceedings of the 2014 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST) Research at Carnegie Mellon University into various PUF implementations found that some error reduction techniques reduced errors in PUF response in a range of ~70 percent to ~100 percent.Bhargava, M. "Reliable, Secure, Efficient Physical Unclonable Functions", Carnegie Mellon University Research Showcase @ CMU, Pittsburgh, Pennsylvania, 2013 Research at the University of Massachusetts Amherst to improve the reliability of SRAM PUF-generated keys posited an error correction technique to reduce the error rate.Vijayakumar, A.; Patil, V.C.; and Kundu, S. "On Improving Reliability of SRAM-Based Physically Unclonable Functions", Journal of Low Power Electronics and Applications, 12 January 2017 Joint reliability-secrecy coding methods based on transform coding are used to obtain significantly higher reliabilities for each bit generated from a PUF such that low-complexity error-correcting codes such as BCH codes suffice to satisfy a block error probability constraint of 1 bit errors out of 1 billion bits.
