People use statistics as a drunken man uses a lamppost; for support, not illumination.
If you needed further proof of Andrew Lang’s quote you needn’t look further than reports in the media this week proclaiming “Christchurch traffic worse than Auckland’s?”
The basis of such a statement? The statistic that Christchurch drivers average 36km/h during peak time versus Auckland drivers who enjoy an average speed of 39km/h.
What a load of complete bollocks if you’re not going to take into account any other factor. How about the average distance that each city’s average commuters have to drive during peak times at average speeds? I bet Christchurch’s drivers spend less time in their cars each day compared to their Auckland counterparts.
We could (moderately unscientifically) compare the journey from each city’s airport into the central city. For Christchurch you’d travel roughly 10kms, for Auckland you’d travel roughly 18kms.
Average time travelling at average speeds would bring you to an almost 17 minute journey in Christchurch versus a 27 minute journey in Auckland.
Media people! Please please please explore an issue with just a tiny bit more balance. Especially when you’re dealing with one-eyed Cantabs!
