Yeah but thats 50% on a bell curve. So think of the average person and that represents 68% of the population. Going 1 standard deviation lower 13% then lower is 2%. Numbers here are generalised*

skozzii@lemmy.ca 3 weeks agoIt’s sad, but the old saying from George Carlin something along the lines of, “just think of how stupid the average person is, and the realize that 50% are even worse…”

That was back when “average” was the wrong word because it still meant the statistical “mean” - the value all data points would have if they were identical. What Carlin meant was the “median” - the value in the exact middle of the range of values. Over the years the word “average” has devolved to either the mean or median, as if they’re the same.

When talking about a large, regularly distributed population, there effectively IS no difference
LovableSidekick@lemmy.world 3 weeks ago
There might be no difference. In memes or casual conversation the difference usually doesn’t matter, but when thinking about important things like government policy or medical science, the difference between mean and median is very important - which is why they both exist.

A joke is definitely casual conversation
Mathematically, the difference becomes increasingly statistically insignificant as your population size increases. Sure maybe there’s a few niche cases where a hundred-thousandth of a percent difference matters, but that’s not even worth bringing up.
The only reason any of you even bring it up is to try and sound smart in a pedantic, “ackshually” way.

Not in all cases. When I teach mean, median and mode, I usually bring up household income. Mean income is heavily skewed by outliers (billionaires), median is a more representative measure.
