Na pesquisa científica, busca-se sempre a excelência na metodologia, visto que tão importante quanto a definição do melhor método é a escolha da escala utilizada. Este estudo tem como objetivo identificar os tipos de escalas utilizadas em pesquisas e suas aplicações. Os quatro tipos de escala mais comuns são: nominal, ordinal, intervalar e proporcional. Entre as escalas de atitude utilizadas em pesquisas científicas, destacam-se a de Thurstone e a de Likert. A escala de Thurstone é utilizada para medir uma provável atitude humana sem indicar a intensidade. A escala Likert é constituída por cinco itens que variam da total discordância até a total concordância sobre determinada afirmação. Ela se difere da Thurstone devido ao grau de intensidade que abrange suas respostas e vem sendo mais usada.

Student ECTS Credit Feedback Surveys are implemented in order to fine tune ECTS credits of courses which are mainly calculated and allocated by the instructors according to the workload components they declared in the course descriptions. However, accumulated experience shows that the current design of surveys requires immense cognitive load on part of the student. At present, survey questions are posed in such a way that it requires the student to undertake a self-appraisal process regarding the workload of learning activities for a particular course. This article discusses an alternative design for adjusting ECTS credits; a holistic perspective based on pairwise comparisons of workloads of courses. Binary relationships are unfolded using Thurstone scaling and then rescaled to ECTS units through a measurement error model. Monte Carlo simulations are used to demonstrate the robustness of the estimators.

Research on the visibility and recognition of homeworkers has largely been done from the perspective of the workers themselves to gauge and document their experiences. Not nearly enough has been done to evaluate the current perspectives of the officials vested with the power to regulate, inspect and enforce decent work characteristics to their work. A lack of research has been identified in the development and use of a measurement scale of the attitudes labour officials may have towards homeworkers. The purpose of this research is to adapt a scale with which the attitudes of labour officials in Zimbabwe towards homeworkers may be measured. The Thurstone Method of Equal Appearing Intervals technique was used to methodically select attitude statements. A total of 36 candidate statements were generated. After analysis, this pool was narrowed down to 20 statements that were used in the final questionnaire. Findings show that these 20 statements were of least variability among judges and...

To investigate cultural lifestyle preferences in different cultural contexts, a forced-choice questionnaire was constructed, based on Thurstone's Law of Comparative Judgement, an almost forgotten statistical method of 1927, which is a useful tool for assessing groups. This study's questionnaire items targeted job and living conditions in the spectrum from traditional to global-ised lifestyles. Subjects were indigenous representatives at the UNO in Ge-neva, and students in Nigeria, Cameroon, South Africa and Germany. The preferences ascertained reflect attitudes on a scale ranging from very tradi-tional to very globalised lifestyles. Although being an uncommon assessment tool, Thurstone's Comparative Judgement indicates to yield highly valid out-comes, as the results of the African university students, though from three different countries, resembled each other, but were complementary to the re-sults of the indigenous representatives, which, in turn, mirrored the Berlin controls' profiles, according to expectations. Findings are discussed in light of the Symbolic Self-Completion Theory.
