What's worse is that half of the students are performing worse than the median.

    Reminds me of an old Carlin joke:

    "Think about how stupid the average person you meet in a day is. Think about it, think about it.

    HALF OF THEM ARE EVEN STUPIDER THAN THAT!"

    But it's an average, there's chance of more than a half (although with normal distribution we should expect average and median to be the same)

    A median is specifically a method of taking an average that always results in half above and half below. Take the total number of participants, divide it by two, then count that number from either end. The middle is the median. It's a more accurate form of averages for statistical analysis.

    Mean is where you add all of the scores and divide by the total number of participants. It's more liable to be skewed by outliers, so not necessarily in the dead center of the list. It's often avoided in statistical analysis for that reason.

    Edit: I just reread your comment and on second glance it seems we're saying the same thing. I should have replied to the commenter below you...

    Given that average can refer to median, and he's saying that half of people are stupider than the average, we can conclude he probably meant the median :)

    Did they stop teaching the difference between mean, median, and mode the year after I left elementary school? It seems like nobody knows that those are all three types of average anymore

    I don't really get your point as under the assumption of normal distribution all three are the same

    Albeit there was another comment about intelligence not being normal distribution which is a bit unfortunate imo

    And practically every time I see someone talk about average it is a mean, a lot rarer it's median, and I never heard anyone talk about mode in general public

    I actually went and investigated this at some point out of curiosity and came across a paper showing that intelligence is not a normal distribution but a sum of TWO normal distributions, the second one much smaller than the first and slightly offset (towards the lower values if I remember it correctly).

    That being so, for the distribution of intelligence in humans the median is not the same as the mean (which is what's commonly meant by "average") so it's slightly incorrect to say that half of people are below average intelligence.

    Now if only we could judge people on actual intelligence instead of just how much we disagree with them...

    I mean, wouldnt that be a worse basis for judgement though? Like, a significant amount a person's intelligence is based on non-voluntary factors, so judging someone for a lower than average intelligence seems unfair in the same way that judging them for being short or looking unattractive or such would be. Further, while a lower intelligence might make it harder for someone to understand more complicated ideas, it isnt a guarantee of them being wrong either, so one cant dismiss the contributions of a less intelligent person as always useless just because of their intelligence. Meanwhile, a person's views are comparatively more changeable, more influenced by that person's decisions, and an incorrect or morally repugnant idea is going to be wrong regardless of how intelligent the person holding it is.

    People aren't judging others they meet on a day to day basis on "repugnant ideals" or moral absolutes. They're judging people based on those people doing something that they don't like. Ninety-nine times out of a hundred people are just going about their day, they're not trying to push their agenda or make you live the way they prefer.

    Really, my criticism was of the basis of the quote, that someone is stupid because of how you met them during the day rather than their actual intelligence level. That someone is dumb because they don't agree with you, or do something in a way you don't like. Which, kind of, is what you're saying. The problem is they're quantifying it as stupidity instead of moral repugnance.

    There are a ton of intelligent people who are absolutely abhorrent. Just because they disagree with you doesn't mean they're dumb... they just don't share your values.

    Excellently said, yes! The vast majority of people in any political system are uncaring if they're propagandized, don't actually care about government "ideals", they care about economics at the end of the day.

    I have a wide social circle, and some of the smartest people I love have very different values than I do when assessing policy, and I still respect them for it, because we can explain why we think so.

    when everything is acting up

    the server, kid, and stage

    sometimes the bravest thing to do

    is turn a single page

    not every bit needs pushing through

    not every load needs borne

    a rest is not a missing note —

    it’s how the song is formed

    you left a little comment here

    a small and cozy light

    and someone read it, felt it land,

    and held it through the night

    so post your little posts, my friend

    the network needs the thread

    a system with no idle time

    is one that’s nearly dead

    Twitter... Jack Kimble is a fictional, satirical account.

    The first "sentence" starts with a preposition; and, yes, the second isn't a sentence. It's more like an interjection, as in, "Behold! 25% of students in the bottom quartile!"

    I'm not a big fan of standardized testing, they evolved from a simple tool of measurement quickly into an industry and a political weapon (teaching for the test). But they do provide a glimpse still of the status of education.

    If he wanted to show the reality of things, he would have quoted the actual percentages, which show how bad it is. In the SAT 41% are ready for university-level math, 64% for reading and writing (only 13% of them completed the essay part), and the ACT is a huge 29% and 39%, respectively. And that's just the kids who took these tests.

    It's always been bad. I remember being surprised when I went to college decades ago and there were remedial classes to get students up to university standards because they were coming out of high school not ready.

    And a quote from a test provider, Brighterly:

    "According to standardized math testing statistics PDF files researched, student performance has worsened since the pandemic and is not improving dramatically."

    We've failed our kids. Many times over. All generations.

    Standardised tests started as tools to do racism without directly doing racism.

    Low test scores in the U.S. actually just measure the fact that it provides roughly the same education to every student instead of what most other countries do and filter students out if their scores aren't high enough in elementary school.

    I would say standardized testing is a way for us to provide transparency about how we are failing our kids. The SAT and ACT stats you used are an example of that. This should motivate us to improve things, but like a lot of modern issues people just don't care enough to make it happen. Even so, being able to cite worsening outcomes supports people arguing for more investment in education.

    I took standardized tests from elementary to college, and I remember their questions being objective, unambiguous, and relevant to learning topics much better than teachers' custom exams. I actually felt well prepared for the SAT/ACT/college thanks to the way they were used.

    Teachers do need some discretion on what they teach, but without good standards you can easily have them just spreading their personal agendas. I don't want students learning about "the war of northern aggression", or that native Americans just chose to move to reservations actually, or that evolution is nonsense, or that abstinence is the only way to be safe regarding sex. Having expectations about what students should know at each grade gives a goal without stipulations on how it's achieved. Standardized tests then just measure it.

    IIRC, they had to explain that the island would not sink due to putting the weight of more troops and equipment on it.
