=+Task 1: I’ve wondered whether musical taste changes as you get older:

my parents, for example, after years of listening to relatively cool music when I was a kid, hit their mid-forties and developed a worrying obsession with country and western. This possibility worries me immensely, because if the future is listening to Garth Brooks and thinking ‘oh boy, did I underestimate Garth’s immense talent when I was in my twenties’, then it is bleak indeed. To test the idea I took two groups (age): young people (which I arbitrarily decided was under 40 years of age) and older people (above 40 years of age). I split each of these groups of 45 into three smaller groups of 15 and assigned them to listen to Fugazi, ABBA or Barf Grooks 6

(music). Each person rated the music 835

(liking) on a scale ranging from +100 (this is sick) through 0

(indifference) to −100 (I’m going to be sick). Fit a model to test my idea

(Fugazi.sav).
