Transcribed Image Text:R3.34. Pubs In England, a Leeds University researcher said that the local watering hole's welcoming atmosphere helps men get rid of the stresses of modern life and is vital for their psycho- logical well-being. Author of the report, Dr. Colin Gill, said rather than complain, women should encourage men to "pop out for a swift half?" "Pub-time allows men to bond with friends and colleagues," he said. "Men need break-out time as much as women and are mentally healthier for it." Gill added that men might feel unfulfilled or empty if they had not been to the pub for a week. The report, commissioned by alcohol- free beer brand Kaliber, surveyed 900 men on their reasons for going to the pub. More than 40% said they went for the conversation, with relaxation and a friendly atmosphere being the other most common reasons. Only 1 in 10 listed alcohol as the overriding reason. Let's examine this news story from a statistical perspective. a) What are the W's: Who, What, When, Where, Why, How? b) What population does the researcher think the study applies to? I c) What is the most important thing about the selection process that the article does not tell us? d) How do you think the 900 respondents were selected? (Name a method of drawing a sample that is likely to have been used.) e) Do you think the report that only 10% of respondents listed alcohol as an important reason for going to the pub might be a biased result? Why?
