In England, a Leeds University researcher said that the local watering hole's welcoming atmosphere helps men get rid of the stresses of modem life and is vital for their psychological 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. "Me n 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.
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?
