Read the scenario below and answer ALL questions that follow

Chris is a researcher in school counselling who is concerned about the stresses experienced by young adolescent students at his school. Chris wants to convince his principal and school manager to provide funding to support a new after-school programme. He decides to gather data on the problems that youth at the school are experiencing to find out what types of programmes are most needed. Knowing that the school board will want to know how frequently the problems occur, he initially decides to gather information through a quantitative questionnaire that measures the number of stressful events youths have experienced. The questionnaire that Chris selects lists many stressful events, such as getting a bad grade, parents fighting, getting into fights with friends, moving or losing someone you loved through death. Youth completing the questionnaire are asked to check off all the events that they have experienced in the past year and to indicate which event was most stressful. Chris will then calculate the percentage of youth selecting each response and report which types of events are most frequent and how many youths are experiencing them. However, Chris also wants to provide greater depth and meaning to his report. To accomplish this, he adds a question asking the students why the event they identified as most stressful was so difficult. Chris plans to select several youths based on their answers to this open-ended question and interview them in depth to find out how they coped with the event. He obtains permission from the school and most of the students' parents to conduct his research study. As he analyses the questionnaire results, he notices that one boy has checked that both his dog and his father died in the past year. Chris decided to interview the boy who explained that the dog had been a gift from his father on his 7th birthday. He and his father often took walks with his dog. "When my father died, my dog comforted me. I always talked with him about my father. So, when my dog died, it was like losing my dad all over again and my best friend." In his school board presentation, Chris presents data from his questionnaire showing the numerous youths reported stressful events involving the loss of a loved one. He illustrates the difficulties experienced by the youth using several stories from his interviews. (Note: He obtained permission to use the stories and carefully protected the confidentiality of the youth by omitting any identifying details). He then makes a request for funding to support programmes on grief and loss for the students.
