Task 1: People’s musical tastes 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 worries me immensely because the future seems 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 20s’. So, I did some imaginary research to find out whether my fate really was sealed, or whether it’s possible to be old and like good music too. First, I got two groups of people (45 people in each group): one group contained young people

(which I arbitrarily decided was under 40 years of age) and the other group contained more mature individuals (above 40 years of age). This is my first independent variable, age. I then split each of these groups of 45 into three smaller groups of 15 and assigned them to listen to Fugazi (who everyone knows are the coolest band on the planet),6 ABBA or Barf Grooks (a less well-known country and western musician not to be confused with anyone real who produces music that makes me want to barf). This is my second independent variable, music. After listening to the music I got each person to rate it on a scale ranging from –100 (please poke a pencil through my eardrum so I don’t have to listen any more) through 0 (I am completely indifferent) to + 100 (I love this music so much, it gives me a tingle down my spine). This variable is called liking. The data are in the file fugazi.dat. Conduct a two-way independent ANOVA on them.
