A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

From Wikipedia:
What you described would be the median, not average. Those can be very far apart, a good example is the distribution of wealth. Put 10 homeless people in a room with Bill Gates and everyone's a billionaire on average.
The median is an average. There's generally three types of average, Mean (what you're talking about), Median (the one they're talking about), and Mode (the one rarely talked about).
Sorry for being nitpicky and thanks for naming them all. I just assume the term average is equivalent to mean average in peoples heads. For uneven distributions, like wealth or life expectancy are I assume, mean average in itself just wouldn't be a useful measurement.
Yes, when most people say average, they mean mean. Few people I've met know the other concepts even exist.
Even Excel has a function called “average”, whereas R uses the “mean” function for the same thing. Interestingly, R doesn’t have a function called “average”, because that term is far too ambiguous to statisticians. I think that summarizes pretty well who these tools were made for.
US public schools taught me that mean=average and the others were themselves, not that average describes any process to find a "normal" value. Just throwing that out there so people know why the conversation above happens so frequently.
The very wiki article quoted says average to mean mean (made explicit later). OP showerthought was calculating life expectancy in a way different than commonly understood. The first nitpick was correct.
Average has a definition of being the mean, median, or mode, BUT it also has a definition that it is a synonym for the mean.

Average life expectancy can be misleading. I did the maths with my grandfather's siblings and him, they had an average life expectancy of like 50. However two died before their first birthday, one died shortly after, then the next one to die was like 58, and the rest were 80-90.
