Task 1: People’s musical tastes tend to change as they get older. My parents, for example, after years of listening to relatively cool music when I was a kid, subsequently hit their mid-forties and developed a worrying obsession with country and western music. This possibility worries me immensely because the future seems incredibly bleak if it is spent listening to Garth Brooks and thinking ‘oh boy, did I underestimate Garth’s immense talent when I was in my twenties’. So, I thought I’d do some research. I took two groups (age): young people (I arbitrarily decided that

‘young’ meant under 40 years of age) and older people (above 40 years of age). There were 45 people in each group, and I split each group into three smaller groups of 15 and assigned them to listen to Fugazi, 3 ABBA or Barf Grooks 4

(music). I got each person to rate it (liking) on a scale ranging from −100 (I hate this foul music) through 0 (I am completely indifferent) to +100 (I love this music so much I’m going to explode). The data are in the file Fugazi.sav. Conduct a two-way independent ANOVA on them. ②
