This is the right answer but maybe not to the right question. For most applications the linearity of variance does not really matter (e.g. when taking descriptives of a sample), at least in the way they are used/taught. Not that many appliers of statistics do computations where the mathematical properties of variance have any significance, and even when it does (e.g. ANOVA), most appliers don't really understand where it comes from.

I think the OP's frustration in how computation of standard deviation as a quantity is just taught by rote in a cookbook manner is quite understandable. If one's not thought more in depth about distributions and estimation of their parameters, it really makes little sense.

Whether the statistics should be taught more in depth is another question. The current state of the mathematics of statistics and probability is such that it needs quite heavy tools to do rigorously. And countless of hours of getting to know the quirky inconsistent notation.

But until it is taught more rigorously, more intuitive measures of dispersion like MAD make a lot more sense for most applications. And I don't think it would be an unreasonable ask for the statisticians to lay out the "porcelain" for working with the more intuitive, if somewhat more analytically inconvenient measures. A bit like we don't require programmers to understand how transistors work.

Long division calculates the multiple at each step; short division just finds the remainder. That doesn't seem that different but when you come to do it algebraically you need to do long division. I did both at primary school (age 10), but it wasn't until 6th form (age 16) that we used long division again, those who hadn't done it at primary struggled a little.

083.28
2.26...
___
7 |583.00

That's short division (sometimes called the "bus stop method" in UK), top line is answer [quotient], next line is "remainders". You say "7 in to 5 won't go; 7 in to 58 is 56 [just from knowledge of times tables, it's 56 tens your dividing], with remainder 2 [write remainder down, usually as a superscript to the dividend]; 7 in to 23 goes 3, remainder 2 [write remainder down]". Now you have the answer 583/7 is 83 remainder 2; but you can continue and divide the 20 tenths by 7, and so on.

Long division:

083.28
2.26...
___
7 |583.00 [<-dividend]
56 [=8x7]
--
23 [2 from subtracting answer to 8x7 {8 is put in answer line}, 3 from the dividend]
21 [=3x7]
--
2.0 [2 is remainder, 0 from dividend]
1.4 [=2x7 is remainder, 0 from dividend]
---
.60
.56 [=8x7]
--
4 [is the remainder in 100ths]

What we're doing is taking five-hundred and saying can we divide that by seven-hundred, we can't. So then we say well how about fifty-eight tens, can we divide that by seven-tens. The tens cancel each other out ( 10/10==1 ), so 58/7 = 8r2 but this is really saying 580/70 is "80 lots of 7" and 20/7 left over. So now we add that 20 units to the 3 units we have already from the dividend we started with, so now we need to do 23/7. And so on ...

I'd do an algebra example but it's a pain in the arse just using ASCII.
It's not really solved on Wikipedia. Wikipedia fights happen all the time in controversial topics, and it's essentially solved by techno-theocracy; moderators show up and lock a contentious topic against vandalism when it's too heated, and whatever the current state of the edit war is gets frozen.
By the way, statistics as its own discipline is taught rather differently from the "here is a toolkit of magic tables and formulas and how to use it" method used when teaching it to non-statisticians. The magical bits actually make sense.

In the US, we call these bureaucrats "judges", and the falsehoods they might combat "libel" and "defamation". No it's not the same, but this doesn't exactly sound like 1984 either.

Frankly, I don't think it's necessarily a bad thing that there's some form of pushback against falsehoods, even for political falsehoods. The risks are overblown; it's not like we don't already have a system of checks & balances for stuff like this - a little more judicial application might help. People imply that the distinction between truth and falsehood is a matter of opinion, and you're doing that too by phrasing things like "bureaucrats decide what is fake and what is the ultimate truth". And yes: if you distill it down to a completely binary choice, there's probably some token of opinion in pretty much any case that matters. But that's a ridiculous oversimplification. Just because there's some tiny amount of opinion in anything, doesn't mean there isn't a significant portion of fairly objective observation in many statements. The plain facts matter too; not just the opinion, and it's just not all that hard to identify lies regardless of opinion. So: yes there are cornercases, but throwing the whole concept of objective fact out of the window because some small details are unclear is ridiculous.

In any case, content platforms -like facebook- do some of this kind of thing internally, without (as much) oversight, with far more impact, even if it's subtler.

Just because it's possible to abuse censorship doesn't mean every possible quality filter must necessarily turn out horrible. Just because opinions may differ doesn't mean there aren't considerable agreements about what's true (and those truths matter, too!). In terms of risks: there's no reason not to spot check + audit; no reason for the moderation to be secret; no reason for the information itself to be completely suppressed (simply not regurgitated without caveats) - all kinds of reasons why this isn't necessarily a problem, and it's IMNSHO obvious that nowadays noise is far more harmful to rational discourse than explicit censorship; and as censorship goes the implicit censorship of unchecked social bubbles is more likely to be misleading than explicit censorship.

Btw, I don't know enough about the singeporean system to have an opinion either way: but this casual disdain for anything that even reeks of censorship just doesn't make any sense.

TEACHER QUALITY

https://faculty.smu.edu/millimet/classes/eco7321/papers/hanu...

> Perhaps most remarkable is the finding that a master’s degree has no systematic relationship to teacher quality as measured by student outcomes. This immediately raises a number of issues for policy, because advanced degrees invariably lead to higher teacher salaries and because advanced degrees are required for full certification in a number of states. Indeed, over half of current teachers in the US have a master’s degree or more.
Teacher experience has a more positive relationship with student achievement, but still the overall picture is not that strong. While a majority of the studies finds a positive effect, only a minority of all estimates provides statistically significant results. Even the subset of studies that use a value added approach and information from a single state produce a highly variable set of results (see bottom panel in Table 1). If anything, the value-added estimates within individual states suggest more strongly that experience has an impact, although still only 41% of the estimates are statistically significant. It is quite likely that a number of these studies lack the statistical power necessary to identify precisely the experience effects.

Or are you saying it was a signal of the end for the specific niche geeky crowds? If so then I guess that’s my point. Google Reader doesn’t and never did move the needle that much.

Every room has a minimum of 7+ sensors (motion, occupancy, light sensor, nightlight, sound, mic, temp, humidity, smoke & carbon (and all related nest sensors like battery, last check, status..., path lighting (not included)). Then light switches are all smart + have occupancy + dimmer level etc... It adds up quick...

I have some crazy node red sub flows where I use state machines to turn on based on conditions and I can do whole home announcements as well as level audio and use it for custom security solution. I have smart bulbs too in some rooms and everything is 100% local with no external dependencies (if voice assistant stops working it doesn't affect anything and I'm going to probably move everything to almond). I built everything around sub flows and I made it easier to debug by adding friendly toggles that actually let me do some crazy accessibility stuff like announce motion or lights turning on etc.. If you were blind you'd know exactly where you were at.

I'm also doing local facial recognition (lots more todo) and I'm starting to integrate those into custom automations based on whose in the room (wife or me). It also greets us when we get home.

I believe the idea of schools being funded by property taxes is that you then spread the cost load out over people of all age groups, in a way to acknowledge that having educated children is a benefit to the community.

This isn’t true.

From the CPC Popular Front funded Brookings Institution.

https://www.brookings.edu/research/how-progressive-is-school...

> School funding systems vary by state, but in the typical state, the financing of K-12 education is shared roughly equally by the state and local governments (with the federal government covering less than 10 percent of the cost). Most states have provisions designed to target additional funding to districts attended by low-income students, with the goal of making up for these districts’ limited capacity to raise revenue through property taxes and other local sources.

> Nationwide, per-student K-12 education funding from all sources (local, state, and federal) is similar, on average, at the districts attended by poor students ($12,961) and non-poor students ($12,640), a difference of 2.5 percent in favor of poor students.

From Merriam-Webster:

https://www.merriam-webster.com/legal/whistleblower

Legal Definition of whistleblower

: an employee who brings wrongdoing by an employer or other employees to the attention of a government or law enforcement agency and who is commonly vested by statute with rights and remedies for retaliation

That is the "legal" definition, but I understood also the "common" definition is such, otherwise any employee that reports to his/her superior/management anything that is not "right" or "legal" or "correct" would instantly become a whistleblower by the sheer fact of reporting that.

So according to Wikipedia all internal inspectors, auditors, etc. in a company would be automatically "internal" whistleblowers.

Sounds like you can just say (as happens) we have to get the answer we're looking for on the "put the answer here" side.

7 + x = 12

"The 'x' represents the answer, so we have to get it on the 'put the answer here side'; lets write 12 = x + 7 ; now we just need to take 7 from the 'put the answer here side' and we're done. But whatever we do on one side we have to do on the other. Take 7 off. 12 - 7 = x + 7 - 7 => 5 = x ... bingo".

Your ex was correct.

What Causes the Seasons?
The Short Answer:
Earth’s tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun’s most direct rays. So, when the North Pole tilts toward the Sun, it’s summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it’s winter in the Northern Hemisphere.
It's all about Earth's tilt!

Many people believe that Earth is closer to the sun in the summer and that is why it is hotter. And, likewise, they think Earth is farthest from the sun in the winter.

Although this idea makes sense, it is incorrect.

It is true that Earth’s orbit is not a perfect circle. It is a bit lop-sided. During part of the year, Earth is closer to the sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the sun and summer when it is farthest away! Compared with how far away the sun is, this change in Earth's distance throughout the year does not make much difference to our weather.
In many businesses, getting permission to buy/license from a new supplier is way more effort than just selecting another option at the cloud provider you're already set up with.
Then why would they care if the domain is .org, .com, or .xyz?

Little-known fact: Windows of today is an entirely different OS than early DOS-based Windows because Microsoft took ownership of the 386-based “OS/2 3.0” codebase it jointly developed with IBM, forming the foundation for Windows NT 3 which all modern Windows is based on. This gave them the huge head start in having a modern enterprise-grade operating system that allowed them to dominate the market.
