Among other things, the proposed investigation is expected to help in assessing the quality and relevance of business research works in higher institutions; assist in repositioning business education curricula to align with academic, regulatory and industry expectations; improve the quality and relevance of research works undertaken in business schools in institutions of higher learning; and stimulate research in cognate areas. The potential advantages of assessing procedural understanding by written tests are also discussed. The study also identified several avenues for further research by using different research methods and examining the impact of strategic decision making in different contexts. %%EOF

INTRODUCTION Validity explains how well the collected data covers the actual area of investigation (Ghauri and Gronhaug, 2005). They indicate how well a method , technique or test measures something. Literature Review The evidence of validity and reliability are prerequisites to assure the integrity and quality of a measurement instrument [Kimberlin & Winterstein, 2008]. After death, palatal rugae significatively change especially in mouths with restorations/prosthesis/missing teeth. 2. Obtained results were subjected to statistical analysis by the t-student test and X-square test with Yates correction (p<0.05). Attention to these considerations helps to insure the quality of your measurement and of the data collected for your study. Validity is the extent to which the interpretations of the results of a test are warranted, which depends on the particular use the test is intended to serve. A good quality of assessment can be seen from high index in validity, reliability, (Bolarinwa, 2015;Mohajan, 2017; ...

Considerable effort has been dedicated to the issue of how to benchmark best practice measures of construction time performance (CTP) for use in the construction industry. The methods used to analyze the test items are item analysis (ITEMAN), two types of descriptive statistics for analyzing test items and another for analyzing the options. Quantifying Home Cooking EnviRonments has applications in nutrition epidemiology, health promotion, and nutrition interventions. Home-CookERITM was further optimized by reduction to a 77-item version, which is now available to researchers. Methods: One hundred and two(33 male: 69 female) patients aged 18 to 45-year-old (mean: 28.39; standard deviation (SD): 8.23) with orofacial pain(pain in the oral or facial area that was experienced by the participant at the time of data collection) were recruited. Background: Orofacial pain remains one of the most complained dental abnormalities that resulted in the limitation of the jaw and facial activities of the sufferer. a) Convergent validity. Qualitative data is as important as quantitative data, as it also helps in establishing key research points.

Experts were invited to participate in a subsequent "respondent debriefing", i.e., short face-to-face or phone interview [30,32,34], lasting up to 15 min, with a member of the research team (SS). Methods: Two reviewers independently assessed risk of bias for 154 RCTs. ).To help distinguish between instrument and instrumentation, consider that the instrument is the device and instrumentation is the course of action (the process of developing, testing, and using the device).

Scale reliability is concerned with the consistency of the research findings, it indicates the stability and consistency with which the instrument is measuring the concept and helps to assess the "goodness" of a measure.
