Factors affecting the price of a used car in Czechia
Dvořáček, Petr ; Polák, Petr (advisor) ; Šťastná, Lenka (referee)
The market of used cars in Czechia, generating an annual turnover over one hundred billion Czech crowns, is visited by hundreds of thousands of people a year and a similar number of used vehicles are sold there. This work tries to find and appropriately evaluate the main determinants that set the price of a used car in Czechia, and thus, among other things, increase buyers' awareness. Multiple linear regression (MLR) and the ordinary least squares (OLS) method were used to estimate coefficients indicating the effect of a given variable on the price. This study uses a unique dataset, which was obtained from the Czech online marketplace advertising used cars Sauto.cz, containing all available information about more than 55 thousand used cars from 34 different car manufacturers. According to the assumptions, the importance and negative effect of variables indicating the number of kilometers driven and the age on the price of the used car was confirmed. Other important parameters that, on the other hand, have a positive influence on the price of a used car are the elements of additional equipment. Higher price of used cars from German manufacturers compared to competing manufacturers was also confirmed and, conversely, cars from carmakers from America or Asia were found cheaper. As a huge number of...

The Influence of macroeconomic factors on performance in eSports
Hlinka, Vladimír ; Šíma, Jan (advisor) ; Voráček, Josef (referee)
Title: The Influence of macroeconomic factors on performance in eSports Objectives: The main objective of this work is to find determinants of success in eSports. Furthermore, interpreting regression coefficients gives us the opportunity to point out the most important factors of success in eSports and also to compare their relative strenght in regression model. The results of the regression analysis will be put in comparison with the outcomes of similiar papers on this topic, mainly focused on the performance in traditional sports. Methods: To analyse our collected secondary data, we use multiple linear regression model. To test some of the assumptions of regression, Pearson correlation coefficient was used. The dataset was tested on the 5 % significance level. The regression model was made via IBM SPSS Statistics 27. Results: There were only 5 independent variables left in the model after testing all the linear regression assumptions. From these 5, only 4 were statistically significant: Population, School enrollment (tertiary), Internet users per 100 and High-technology exports. Population and School enrollment have the most relative strenght in the regression model. Many authors mention GDP per capita as an important predictor of success in traditional sports, however this study does not...

Evidence concerning pupils'preconceptions of intellectual disability in the context of the paradigm shift in today's education
Pivarč, Jakub
This dissertation thesis is designed as a theoretical and research survey focusing on the currently marginalised issue of intact pupils' preconceptions of intellectual disability. The survey aims to outline the concept of intellectual disability concisely and to accentuate the current paradigm shift in education with regards to integration and inclusion. Particular attention was paid to the theoretical and epistemological basis of preconceptions as well as to the current state of scientific knowledge of the presented area. Research was conducted in order to analyse and characterise intact pupils' preconceptions of intellectual disability. Furthermore, the empirical study aimed to determine whether pupils' preconceptions differ depending on their gender, year of school attended and the declared experience of persons with intellectual disability. A transversal quantitative survey was conducted at 22 mainstream basic schools in the Czech Republic. The research sample consisted of 2230 intact pupils attending the 5th , 7th and 9th forms of basic schools. Data were collected by means of mind mapping and non-standardised questionnaire of our own construction. The findings demonstrate that pupils perceive the phenomenon of intellectual disability in terms of medical paradigm (emphasising the...
