No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

Mode is a kind of average. I infer that you mean "mean" when you say "average" here.
The mean takes into account outliers in a way that the mode doesn't.
The joke about the average number of legs among humans being less than 2 describes a situation where mode provides more meaning than mean. In the case of scattered values, mode makes less sense, such as the average net worth of the people in a country.
I don't know why the mean is the "default" average. In many situations, the mode or median makes more sense.
Mean is the default "average" because it's easy to calculate and were taught it first in school. Like, years before median or mode. That's it, that's the whole reason.
That makes perfect sense to me. I should have known it was that boring.
Poor old Chebychev is not getting much love here is he.
I guess people might think he was a fan of inequality. (sorry - maths joke, at least I didn't do the one about the LOL numbers).
I didn't get that far in probability and statistics. I know of his polynomials, but that was a long time ago.
Mode also is only similar to median in a normal distribution. Anything else and mode and median are very different.
And the mean average makes no sense here either, which is why incomes and wealth are almost always quoted as medians instead of means, unless they're totals which is a roundabout way of reporting the mean (if you know the population baseline).
The more unequal a country, the larger the difference between mean and median incomes.
Sorry, i meant mean, but yeah mode definitely seems better to me, you are very unlikely to find a person/thing who/that has average qualities/stats
Edit: mean only seems good to create kind of a middle line of some sort
Now I understand better how you're thinking. Indeed, the notion of "what the average person has" is answered better by the median, but the notion of "What's most typical" is answered by the mode.
Actually I think that the notion ‘what the average person has’ is bettered answered by mode, I feel like mean is better for kind of plotting a data or points to find a ‘trend’ or something like that, I am hella confused now actually
The mode can't hope to answer how much money the average person has, because there are far too many possible values.
The mean answers how much money people have on average, but the outliers exert too much influence to answer how much money the average person has.
The median moderates the influence of both the very rich and the very poor, so it better approximates the amount of money that those in the middle of the population have, which is what 'the average person" tends to be.
For populations where the number of possible values is much lower, the mode and the median tend to be closer to together. Emphasis on "tend".
Well, the middle line is the median. 😉
