In order to verify the reliability of the questionnaire, 40 questionnaires were distributed and collected among the statistical population, and Cronbach's alpha test was performed. If Cronbach's alpha is more than 0.7, the reliability of the tool is confirmed. In this research, the obtained alpha is equal to 0.73, which is more than 0.7. As a result, the reliability of the studied questionnaire is confirmed.
