Our first step was to identify a topic which students have or faced or experienced in their lives. We then proceeded to put questionnaire together to understand students’ situations. We chose our target which was students between the ages 20-25 taking a psychology course. We explained the survey and its significance for our research, so that the participants would consider putting enough efforts when answering. After this stage, we asked our participants to kindly fill out the questionnaire within 10 minutes and take the opportunity to ask us questions if they did not understand. We accomplished in having 17 completed questionnaire at the end.

Our first step was to identify a topic that students have either faced or experienced during their lives. We then proceeded to put a questionnaire together, so that we could find out and try to understand the different situations that students are in. We chose to survey students between the ages of 20-25 who were taking a psychology course. We explained the survey and its significance to our research, to encourage the participants to put more effort into answering our questions. After this stage, we asked the participants to kindly spend 10 minutes filling out our questionnaire and not to hesitate to ask us any questions if they did not understand anything. When the time limit had finished, We collected a total of 17 completed questionnaires.
