The diploma thesis is focused on the influence of advertising on a selected target group. It deals mainly with the impact of selected tools of marketing communication on the target group, which in our survey are men and women.

In the practical part of the diploma thesis, a marketing survey was carried out by means of a questionnaire, which was sent to the respondents in electronic form. The data obtained through the questionnaire survey were evaluated by frequency tables and graphs. The survey was also aimed at the evaluation of hypotheses, where we used correlation analysis and calculation of the correlation coefficient. At the end of the thesis we present the results of the survey.
