Improving the accuracy of a survey is the focus of Mark S Litwin's book, which shows how to assess and interpret the quality of survey data by thoroughly examining the survey instrument used. He explains how to code and pilot test new and established surveys. In addition, he covers issues...
A good survey response rate can vary widely depending on several factors, such as the target population, survey distribution method, the topic of the survey, how the survey is administered, and the statistical validity required for the results. Qualaroo surveys offer a versatile feedback solution ...
while VR attempts to digitally simulate an entire environment. Both are beginning to transform corporate learning by providing virtual hands-on experience with the tools and procedures employees need to learn for their jobs. The use ofAR and VR in HR-driven trainingcould help avert a knowledge...
Having enough people respond to your survey is essential. Here’s the need-to-know on response rates and how to boost them.
Degrees of freedom is the number of values in the study that vary freely – in every test of the data. While seemingly random, the values are of critical importance when evaluating the validity ofH0. Result Interpretation Interpreting the results isn’t very complicated. All you have to do ...
This study aims to examine the validity of self-reports as a measure of mathematics teachers’ TPACK, by exploring the correlation between teachers’ scores on a self-report questionnaire and a knowledge test. Crucially, the items in both instruments refer to the same specific mathematical content...
It can be hard to find the perfect sample size for statistically sound results. Here we reveal methods and tools for effective sample size determination.
This study investigates the role of institutional quality in the cost efficiency of social services provided by local governments in Italy. Using a newly d
In order to assure the reliable measurement instrument the development of a multi-item scale for the construct must show strong evidence of reliability as well as convergent validity in a research sample.We test our conceptualization using data from a survey, conducted in the Slovenian market among...
