@@mehwhyausername1 tbh I'm guessing statistics is taught less in high school than geometry not because of any point about practicality, but because it it's messy - it's less to do with solving some puzzle that has a precise solution, and much more about appreciating what various values, indicators and formulas mean in terms of interpreting the data. I can feel the confusion and wild questions among students (especially about whether something is the best approach to interpret the data, whether it really represents what it claims to represent, and whether the conclusion is properly justified - way more qualitative in nature), and I remember how even teachers get it wrong, especially interpreting the terminology into context. Then again, it has to be done some time, and high school is probably the best place to learn it cos the students have time and are also of a decent caliber.

I agree; the need for instruction and erudition in probability theory, statistics, and logic is even more clarified and poignant in the last number of years. specifically, there is a pathetic lack of epistemological thought in America, which is ruining our culture and economic competitiveness on the global stage; it's also hampering innovation efforts and entrepreneurial pursuits in technology and business, and leading to lossy events, such as people easily scamming others, or people "investing" in extremely risky assets without knowing the likelihood of success.

I like the plane crash example and I think it relates to cassino and roulettes. A lot of people think that because the ball hit let’s say red 10 times in a row, the probability of it being on red again is extremely small and well, it isn’t. It’s true that the probability of hitting red 11 times in a row is really small. But as soon as it has already happened 10 times, the probability of the next one being red is roughly 50%.

@NealBurkard-ut1oo 10 ай бұрын

Yeah, I believe that's called a Markov chain. Each roulette spin is independent of the previous spin but we can still use the chain to predict the odds the next 10 spins are red. I've taken a decent amount of Stat classes in college and I will probably will never play a casino house game, the payout are always lower than the odds of winning. I do play a lot of poker but that's not a house game.

This was great. People have so many serious misconceptions about statistics, and often their misconceptions lead them to conspiracy theories and other dangerous beliefs because they see what seem to be impossible coincidences that are in reality, just random patterns being detected among the noise of vast numbers of independent events that naturally occur. Some of this was demonstrated by the questions asked here. Jeffrey did a quite excellent job of explaining, but people really need to be educated better about these things.

I think it has more to do as painting people as "establishment". So in this case a right winger might say that this guy is just pushing a narrative that crime is down historically (which it is). So instead of attacking this guy in particular or even the math, you go all out and say "they are pushing a narrative down your throat". So when say a virus has a random mutation and become more infectious, it then becomes easy to say things like "the Chinese created the virus" or "the virus happened in the election year on purpose". It all comes down to "don't trust them, trust us to tell you what reality is".

As someone with a math degree I can tell you, you don't need to be technically proficient to use common sense. Not everybody needs to take a full stats course (though that would be awesome). It's just not a viable strategy. I wish it were not true, but not everybody has the capacity to take those kind of courses. I'm not saying that people are too dumb, I'm saying that we need to focus more heavily on the critical thinking part of the picture. I think a good course would be one were kids are guided on how to spot fake news and how to identify good sources. For example, I'm not a doctor so I will defer to the consensus of medical experts about medicine. It would be great if everybody was good at stats, but the best we could do is at least make people better at navigating a world with constant info being tossed around.

I am SO glad he brought up what he refers to as the "out of how many" issue. It is, likely one of the most compelling reasons for false convictions in the US. It happens ALL the time in all kinds of courts. The Disney example is so useful too. Linked to confirmation bias, when we see something we think is rare, we forget how many chances we had to see it, and how many other 'things' we would have felt that special about that we didn't see. Great great video.

@jonatanrullman 2 ай бұрын

Not sure it was the best example though. The case in question is notable for the statistical error and deservedly considered a miscarriage of justice. But the odds of it happening by chance twice in the same family is still staggering. In the US there is, with recent statistics, only about 3000 SIDS-like deaths per year (and not all of them actual SIDS) out of about 3,5 million births. I'll let someone else calculate the odds of that happening twice in one family without an underlying cause (since the point here was the pure statistical pronsbility) but lets just say it's not an everyday occurance. So while a good example of bad statistics and flawed reasoning, it is hardly a good example of the out of how many problem and it is certainly a stretch to say it is likely to occur. The Disney example though, I thought, was excellent for that point.

I don't think too many people are changing their votes, but you are correct that polling has an effect.

This kind of probability error is really important in DNA cases as well as those are usually determined to one in a few tens of thousands of people at best. It would be a really wild coincidence to get fingered for a crime by some other means and have your DNA be that close - but if you were already nabbed because you were in the same minority in the same general area where you might be related to a lot of people nearby, or if you were grabbed out of a DNA database on a partial match with no other evidence against you, DNA is not necessarily the smoking gun most jurors are going to think it is if they don't understand both the science of DNA analysis and the statistics (which is why you need a better defense attorney than you're likely to get).

11:23 - I’m sure he skipped over it in the interest of time/simplicity, but it’s worth pointing out that birthdays aren’t equally proportioned, i.e., there are some days of the year that more people have birthdays on than others, and that can influence the calculation if you want to go that deep.

@purplegill10 2 жыл бұрын

Moreover, the time when parents actually conceive their children isn't random either. Given that they're all in the same generation, perhaps holidays, honeymoons, birthdays, or even some kind of wild tiny genetic factor all played into it and any gigantic number of other variables as well.

More babies tend to be born in late September and early October, as a result of conceptions in January. February 29th is the rarest birthday. You also notably get slightly fewer babies born on Christmas day and new years and more born slightly before and after, as a result of some parents choosing not to induce births on those days. In a given year you also get more children being born on weekdays, but that obviously doesn't effect birthday frequency over multiple years, as whether a date is a weekday or not varies year to year.

@nmd4332 2 жыл бұрын

Thanks , just about to do 1st yr stats course this trimester, was good to check and reinforce my own knowledge. The basis for much of this is to assume the event is random, but also often the result(/s) fall within a normal bell curve. I normally use red black in roulette to demonstrate independent events and some common fallacies. For example many will bet red if black has come up a lot, the chance of red/black is equal and for the next spin is always equal.
