We present the scale development and refinement process in which we measure for validity and reliability with multivariate statistical methods (Explanatory Factor Analysis, Confirmatory Factor Analysis, and Structural Equation Modeling using Partial Least Squares). Finally, we discuss measurement assessments ...
定性研究经常使用灵活的数据收集方法,需要表达出从参与者的角度来理解问题,并强调时间发生的背景和意义。定性研究常用的数据收集方法为:participant observation, focus group, qualitative interviews, discourse analysis, documentary analysis, and visual methods。其中最常用的方法是访谈(Qualitative Interviews) 。定性访...
In this study we aimed to explainthe reliability and validity concepts by giving examples.It is possible to evaluate the reliability and validity of aninstrument by scientific methods. If we speak of reliability,we have to mention stability (having the same results inrepeated measurements from the...
On one end is the situation where the concepts and methods of measurement are the same (reliability) and on the other is the situation where concepts and methods of measurement are different (very discriminant validity). Next topic Conjointly is an all-in-one survey research platform, with ...
The term “reliability coefficient” actually refers toseveral different coefficients: Several methods exist for calculating thecoefficientinclude test-retest, parallel forms andalternate-form: Cronbach’s alpha— the most widely usedinternal-consistencycoefficient. ...
