Abstract:

The paper describes the results of a research study, which examined the degree of dependence of 18-year-old grammar school students in the Czech Republic on computer games. In the research we used a quantitative research strategy with an own questionnaire to identify the degree of addictive behaviour in students in relation to computer games. The research sample consisted of 525 students in grade three of four-year grammar schools (or an equivalent grade of multi-year grammar schools) from 10 randomly selected schools. The aim of the subsequent statistical analysis was to identify possible groups of 18-year-old pupils according to their addictive behaviour. In the research we used the following result processing methods: K-means cluster analysis and globalized cluster analysis, Student’s t-test and analysis of variance ANOVA; the analysis of nominal data was performed by means of the Chi-square test of independence.
