Many people love their mobile phones, which is rather worrying given some recent controversy about links between mobile phone use and brain tumours. The basic idea is that mobile phones emit microwaves, and so holding one next to your brain for large parts of the day is a bit like sticking your brain in a microwave. If we wanted to test this experimentally, we could get six groups of people and strap a mobile phone on their heads (that they can’t remove). Then, by remote control, we turn the phones on for a certain amount of time each day. After six months, we measure the size of any tumour (in mm3) close to the site of the phone antennae (just behind the ear). The six (theoretical) groups experienced 0, 1, 2, 3, 4 or 5 hours per day of phone microwaves for six months. The data are in the SPSS file “Tumour.sav” (available on NILE). Investigate the relationship between tumour size and phone use using an ANOVA.
