The developed measurement scales that reflect the attributes of the performance value consist of ten items (seven and three items, respectively). Both measurement scales possess adequate psychometric characteristics and are confirmed for their reliability, convergent and discriminant validity and ...

Ratio scales are those that have all the qualities of nominal, ordinal, and interval scales, and in addition, also have a “true zero” point (where the value zero implies lack or non-availability of the underlying construct). Most measurement in the natural sciences and engineering, such a...
the “guessing” technique of measurement is unreliable. A more reliable measurement may be to use a weight scale, where you are likely to get the same value every time you step on the scale, unless your
Section III: Nonexperimental Research Designs Alternative formulas for computing a correlation with many scales of measurement exist, as identified in Table 8.2; however, each of these alternative formulas was derived from the for- mula for the Pearson correlation coefficient, so only the Pearson ...
Rating scales are commonly used as measurement instruments in various kinds of questionnaires and quality of life assessments but also in clinical trials for evaluation of outcome or functioning. There is also an ongoing development of statistical methods for analysis of ordinal data. Hence, the users...

The main limitation of the citational lensing framework is one of measurement. Textual similarity between countries is an unavoidably noisy signal, and this affects the comparison with citations downstream. So, even though it is correct to say that the international inequalities revealed in our ana...
In biostatistics (60 contact hours), emphasis is put on various forms of data, scales of measurement, and data conversion between different scales. Research methods and biostatistics courses, which are covered in semester 1, provide a strong foundation for the development of research proposals. ...
