RustyBertrandI think I see the problem.
Lydia T. Pott@RustyBertrand Why βespecially womenβ?
PeteBecause they don't understand the overlap between Gaussian distributions.
Almost every man/woman has a corresponding woman/man with similar maths ability. There are just a few at the very extremes of ability where there is less correspondence. These extremes are not good indicators for the general population.
Incredibish@RustyBertrand That has to be a joke headline, referencing the story. It can't be that bad, Shirley...
Leendaal@RustyBertrand missed opportunity for the headline: majority of Americans dislike math

odo2063@RustyBertrand Depends on what the 6 said. If everyone each had a different opinion than 4 is a majority.π€·
StarkRG@odo2063 @RustyBertrand No, a majority is more than half. It doesn't matter how the rest of the group is divided, if it's less than half, it's not a majority.
rob@StarkRG @odo2063 @RustyBertrand it is in first past the post politics, which may be where some get their maths from.
@odo2063 @robparsons @RustyBertrand Apparently the US has a different definition of the word than everyone else who define it as more than half. In math, though, majority always means more than half, even if you're American.
@StarkRG @robparsons @RustyBertrand In a two party system majority means absolute majority, wouldn't make any other way. Ops picture implicates that there are more than two partys, otherwise four of 10 couldn't be a majority.π€·
@odo2063 @robparsons @RustyBertrand In a plurality voting system like the US has, it's not uncommon to elect people without having a majority vote. With an instant-runoff system you'll always elect a candidate with a majority of votes. Single transferable vote systems are better in that they're less able to be gamed, but that requires being able to elect more than one candidate at a time.
The original post, though, is specifically about math, not electoral systems.

The US has a different word for the same definition as majority (plurality). Everywhere (including Maths) absolute majority is more than half (the definition of plurality includes a reference to not being an absolute majority) https://dotnet.social/@SmartmanApps/111552092331147428

Attached: 1 image @[email protected] @[email protected] @[email protected] @[email protected] That appears to be a US version of "majority"
@StarkRG @RustyBertrand I might be wrong but i think defined "the majority".
@StarkRG @odo2063 @RustyBertrand
No, a majority is the most. An absolute majority is more than half. It can't be an absolute majority, but it could be the majority - we can't know without knowing what the other numbers were.

@SmartmanApps @StarkRG @RustyBertrand Well, so the indication "4 -> majority" is that the other 6 had 6 different opinions or at least not more than 3 had the same.π€·
ΰ²ΰ²Ώΰ²°ΰ²Ύΰ²ΰ³ πΉβπΎβπ±π΅πΈ (he/him)@odo2063 @RustyBertrand No, it is a plurality. And yes, I'm American and still use majority the way it is intended to be used (> 50%).
@chiraag @RustyBertrand definition says that's the sameπ€·
Stefan Sommer@RustyBertrand @RustyBertrand weeeel, if 4/10 hate it, 3/10 love it and 3/10 don't care, the 4/10 would be a simple majority.
VelteropββπͺπͺπΊπ³π±π¬π§π©πͺ@senorverano @RustyBertrand True for some political systems, where simpletons do believe they are the majority; not for maths.
@villavelius @RustyBertrand ok, maybe it's also a language thing, in English what I meant would be called a relative majority ("a subset larger than any other subset but not necessarily larger than all other subsets combined, and not necessarily greater than half of the set.")
@senorverano @RustyBertrand I know; the kind of FPTP 'majority' that is passed off as 'democracy'.
Perhaps this deserves consideration: https://www.goodreads.com/book/show/30957274-against-elections

@senorverano @RustyBertrand And indeed, language can be confusing. I've seen a step-father being described as a "relative relative" π
@villavelius @RustyBertrand I totally agree that FPTP is not democratic.

British Tech Guru@RustyBertrand The problem is not the subject but the God-awful teaching of the subject.
@britishtechguru @RustyBertrand
From what I've seen with order of operations questions I can tell you it isn't the teaching, but adults who've forgotten what they were taught (I even had one say it wasn't taught in their country, but when I looked up that country's syllabus it absolutely was in there).

I was definitely taught maths but the foundations were poorly taught by disinterested teachers more interested in drawing a wage than in teaching.
I had mostly teachers that were not good. I do remember two when I was in college. One was Dr Jefferys who was absolutely phenomenal and made it all so clear. The other was Mr Wathan an industrial chemist my dad hired to help me achieve a better understanding of what the teachers in school failed to do.
@britishtechguru @RustyBertrand
Yeah, I had a teacher like that in Year 10, then I got really sick for a while and got tutoring at home and did better in Maths. Thankfully very few teachers like that, but having poor teachers doesn't mean the subject itself is taught poorly or not at all (which I've had some people try to claim. See my syllabus example).

Ζ§ΖΏΡ¦ΟΙβΡ¦ΰ¨ΉΡ€Κ@RustyBertrand Yes, it's that they can't spell 'maths'.

@RustyBertrand
In fact, I'm beginning to wonder whether "math" and "mavity" come from the same alternative reality in which, basically, any old shit can happen.

MayhamMonday@RustyBertrand I think that's referred to as conservative math!
Andrew Molloy@RustyBertrand Well, don't keep it to yourself, share with the rest of us. π
@RustyBertrand It's not even four out of ten, it's *almost* four out of ten. Probably at least 35%.

cuan_knaggs@RustyBertrand story from my high school maths teacher: she was once berated at a PTA meeting for not doing her job because half the classes marks were below the class average
adamrice@mensrea @RustyBertrand You must be from Lake Woebegon, where all the children are above average.
Khleedril@RustyBertrand Is this an example of bad maths, or bad English?
