Item analysis as a tool for the evaluation of didactic tests: the example of the course Statistics for geographers
Novotná, Kateřina ; Netrdová, Pavlína (advisor) ; Pěnička, Jaroslav (referee)
In today's education system, we often encounter poorly created didactic tests that do not actually test the knowledge and skills acquired through teaching, or only test them to a limited extent. For example, if items for closed-ended questions are unprofessionally created, students may even guess the correct answers without having any knowledge and skills in the subject area. The aim of the bachelor's thesis is to evaluate the quality of closed-ended questions with a range of possible answers on the example of the final tests of the course Statistics for Geographers and, based on the obtained results, to recommend adjustments to specific items. The evaluation will be done based on item analysis using the ShinyItemAnalysis web application. In the case of poorly functioning questions, based on the results of the analysis, their modifications will be proposed so that they are more suitable for didactic testing. In the theoretical part, the bachelor's thesis will focus on the didactic test as a specific evaluation tool, its forms, individual types of test tasks and recommendations for their creation. Everything will be supplemented with specific examples from the field of statistics. The space will also be devoted to techniques of guessing answers, characteristics of test tasks and test theories....

Hedonistic motivations for shopping - scale localization
Ježek, Michal ; Remr, Jiří (advisor) ; Hendl, Jan (referee)
(abstract) The thesis deals with motivations for hedonistic type of shopping with a focus on their measurement by using a multidimensional scale designed and validated by Mark J. Arnold and Kristy E. Reynolds in 2003. This tool contains six constructs for which the author examined their transferability to the local environment of Czech consumers. The aim of the thesis was to convert the scale into the Czech language and into the context of the Czech consumers and their shopping behavior. There were analyzed cognitive interviews, which were focused on the understanding of the statements on the scale and their adjustment for the following questionnaire survey. This was conducted on a representative sample of the Czech internet population. Furthermore, statistical analysis was carried out with the focus on reliability and validity of the translated scale. Although the research does not primarily aim at creating a typology of shoppers or describing in detail the characteristics of Czech consumers, the results of the analysis indicate that Czech population's thinking about shopping is quite like of consumers in collectivist societies. At the end of the thesis, the final and modified scale is introduced containing five constructs instead of the original six. This instrument has been shown to be...

Statistics in educational test development
Otřísal, Václav ; Pecáková, Iva (advisor) ; Sixta, Jaroslav (referee)
The paper deals with a justifiability of the application of statistics in the process of test development. It also aims to show possibilities of its application on the final test version. The first part of the thesis brings up the fundamentals of test development theory. The second part aims to describe general impact of statistics application on the test qualities. It further focuses on item analysis as one of the tool to evaluate test items qualities. Among others it includes information about reliability and validity analysis so as about the test equating methods. The analytical part contains analysis conducted on the OSP test. The analytical part also deals with predicted test validity and with the quality level of data gained from pre-testing.
