Statistics Rant
-
So many articles that give statistics refer to the median of this and the median of that. Why does no one give averages anymore? And no, a median is not the same as an average. I suspect that more and more writers *think* that median = average.
The difficult we do right away... ...the impossible takes slightly longer.

Maybe because median is more meaningful than the average (in some cases)? Just a thought. You probably know the old story about Bill Gates walking into a bar. Also average household net worth in US is something like 750000$ while median is only around 130000$.

Generally speaking, the median is more useful with a data set that has a large range because it minimizes the effects of large outliers. Income is one very good example of a data set where it is helpful because there is essentially no upper limit to it so the extremely large-income outliers will have an undo effect on the "average" income value.

Like with many other things, both have they usage and are the best when appropiated. You can't put nails with scissors and you can't cut a paper with a hammer. People need to learn the differences and use them in the right context.

You use what serves your goal the best. If your country has a super-super-rich elite, you use average if you want to show how rich your country is. You use mean if you rather want to fight for social reform in your country. If you are a teenager, your parents will use the average age of sexual debut to tell you that your are too young to go to bed with your lover. You will argue that more than half of the kids your age have an erotic life. Here in Norway, the standard of living is so high that very few people ever reach it.

You can if you try really hard. Herself has used scalpels to open paint tins, side cutters to force screws in, and a lump hammer as a stapler ... :sigh: (I hide my good tools these days, and leave a decoy set out for her to abuse.)

To the best of my knowledge, median is more robust to outliers. Let's have 9 measurements of something which are all equal to 100k and one equal to 1B. If we could justify that such an outlier is some measurement error, we could exclude it, but if we couldn't, we must deal with it as is. Now we need to find some "typical" single value which describes this sample in the best way. Their average (mean) would be (9*100,000 + 1,000,000,000)/10 = 100,090,000. At the same time, median is 100,000 which is closer to reality, as for me.

And they now site stats without a basis like a graph trending over time for example. "We said it, believe it, don't think to wonder why.

Can't ignore the possibility they just do not know the difference. Especially since they might be pulling from another source and even that source might not know the difference.
For journalists, that is highly probable. With one minor comment: In Norwegian, 'average' (or in Norwegian: gjennomsnitt) is the common, everyday term that everyone knows and uses. I'd guess that 80% of common people would not be able to correctly explain what 'median' is. Maybe 'median' is more commonly known in English speaking countries, but my impression is that 'average' is a more common term in English as well. An uninformed journalist would be more likely to use 'average', because that is what he knows and understands. And then: Maybe he doesn't really understand 'median', but for that very reason he may be using it to make it sound more 'advanced' and impressing. That could very well happen here in Norway!

For those of you who can make sense of Swedish, and enjoy standups about statistics: Om sannolikhet (About probability)[^] will give you a good laugh (even with this worn-out-VHS-tape-quality from 1969). There are so many puns and so much word play that any subtitling to English would be losing a whole lot of it. It looks as if noone has given it a try. Sorry for you non-Swedish speakers.
