Thanks to those who nominated in last week’s Stat of the Week competition.

This week we’re awarding Lindsay Mitchell’s nomination of the NZ Herald’s editorial which stated that “The vast majority of child abuse is perpetrated by men.”

There are numerous official sources that disprove this claim. For instance: Fig 7. Number of female and male abusers of specific types of abuse and neglect 2006 (pg 117) and Apprehensions for assault on a child (pg 10)

This isn’t a new bad stat, but keeps cropping up in the media.

Thanks for all those who nominated in last week’s Stat of the Week competition.

This week we’re awarding Nick Iversen’s nomination of the NZ Herald’s article “CEO Pay Survey: Salaries stall for NZ’s top bosses” with some nice re-analysis:

The Herald says “the value of the average chief executive pay packet has dropped” and quote the drop in average pay as 0.4%

That’s one way of looking at the data. Here’s another way:

Of the CEOs surveyed 13 had drops in pay and 22 had pay rises. The median pay drop was 7%, the median pay rise was 18.5%.

Of if you prefer mean the mean pay drop was 13.5%, the mean pay rise was 26%.

So most of them had pay rises and the rises were higher than the drops. Looks to me as if the CEOs had a very good year.

One might argue that that this is just an arithmetic blunder, but it does raise (the usual) questions of means and medians.
