50% would be wrong if you said above-median driver.
- nostrademons 16y agoYeah, if you take average=mean, then well over 50% of drivers are above average.
- jcl 16y agoStill, it could be even higher than 50% wrong, since sometimes the most capable people underrate their ability: http://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect http://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect
- amalcon 16y agoMedian is better than mean as a metric for "average goodness of driver". To take a median, you only need a strict ordering; to take a mean, you need to quantify. Any reasonable method of quantifying how good a driver someone is will be heavily influenced by environmental factors. The worst driver on an infinite, featureless plane would be involved in fewer accidents than the best driver in, say, New York.
