I calculated the mean, mode, median and range of my data and found out that the mean is inappropriate. For example, with the people who travelled by car, the mean was 7.35, but you can't have 0.35 of a car trip, because it has to be a whole number. The mode and the median are the only ones we can use BUT the mode is the most appropriate because what I wanted to find out was the most re-occurring method of transport.
