Background & aim: In some situations in quantitative or qualitative research, complementary tools would be of great help in data collection. Vignette is a data collection tool, which has been used for over 50 years in different disciplines including health sciences. Nonetheless, there is a paucity of information regarding this method. With this background in mind, the ...

In machine learning from numerical data, usually the target concept is a numerical function that facilitates quantitative prediction. In contrast to this, we consider qualitative data mining which aims at finding qualitative patterns, or qualitative relationships in numerical data. We present one approach to qualitative data mining, in which the target concepts are expressed as qualitative deci...

Though very often quantitative problem solving is accentuated in physics instruction, psychological as well as educational research indicates that this emphasis is misleading. In an experimental study, we compared physics instruction with a focus on quantitative problem solving to physics instruction with a focus on qualitative problem solving. Initially, students were taught quantitative as we...

In this article the methodology proposed by Li and Wang for mixed qualitative and quantitative modeling and simulation of temporal behavior of processing unit is reexamined and extended to more complex case. The main issue of their approach considers the multivariate statistics of principal component analysis (PCA), along with clustered fuzzy digraphs and reasoning. The PCA and fuz...
