Are You Better At Math Than a 4th (or 10th) Grader? 845
New submitter newslash.formatb points to this Washington Post blog post, which "discusses the National Assessment of Educational Progress test (specifically, the math part). One of the school board members took it and was unable to answer any of the 60 math questions, though he guessed correctly on 10 of them. He then goes on to claim that the math isn't relevant to many people. P.S. — if you want to feel like Einstein, check out some sample questions." Maybe this is mostly about the kind of life skills that are sufficient to succeed in management.

Bad, very bad, examples. Psychiatrists have a LOT of statistics in their degree.

Assuming all questions had four options and the answers were uniformly distributed, then yes, the "expected value" is 15.

For normally distributed data (which I would expect the scores for such a test with random answer selection), 68% of the results are within 1 stdev, and 95% are within 2.
So, a score of 10 doesn't seem out of place at all. (And this is all high-school level stats, mind you, sticking to the Probability 101 theme here.)

As someone with a masters in maths and PhD in physics, this is the same way I did the calculation. In fact, I suspect it's the way anyone who knows some more advanced maths would do it: What you've effectively done (in maths language) is:
1) Use the associative property of multiplication and its inverse: (AB)C=A(BC).
2) Rewrite the unknown product 47*3 in terms of two known products, by first rewriting 47=50-3, thus (50-3)*3.
3) Expand the bracket: 47*3=50*3-3*3.
Now this is much akin to the 'normal' method used to teach kids, except they always expand their brackets in terms of positive numbers broken up by powers of 10, ie 47=40+7, however from a mathematical standpoint there's no reason not to use any splitting you like, only the expedience of learning a limited number of multiplications.
The true gift of good mathematicians is not only being able to make these thought processes, but properly explain them so that others can too. Far too often maths as it is taught is just a voodoo recipe for performing calculations rather than a well explained, reasoned setup. This is fine for people who merely have to perform the function (much as you don't need to know the workings of an internal combustion engine to drive a car) but if you want to derive a deeper understanding of what's going on its woefully insufficient.

I'd done fine at maths throughout school until mid-way through higher (roughly final year of highschool level) I was suddenly struggling. There were whole sections of the syllabus where I just couldn't see it. There'd be a question and I just couldn't grasp how to get from the info given to the solution required. I failed my mock exam, and not just marginally.
I was a "B maybe A" in all other classes. The teacher was pretty good and everything.
As luck would have it, my dad was friends with an engineer who offered some tutoring. First couple of sessions were straightforward and he said he didn't know what the problem was. He was giving me stuff that was as hard as it gets in the exam and I was able to solve them and explain it, not just following memorised procedures. Next session we came across something I just had no idea. He walked through solving it and one of the steps I was just what? I can't even remember what it was, some concept that once you have it you don't even think about it, like how you can multiply both sides of the equation to simplify. He'd barely started explaining it and I was like ooh - it just clicked.
We abandoned the sessions soon after that because I'd literally gone from being an D/E to a strong B student in but a moment of comprehension. I must have simply been off sick that day or something, and the specific weakness never picked up in marking - perhaps due to rather large class sizes. I suspect that's not the real root though. Mid-way through the year, the classes were shuffled and my desk partner was changed from a friend who I worked well with to someone I didn't know and pretty much didn't work with at all. It was probably about this time my grades began to fall and my friend's grades slipped as bad as mine (he was the other mock fail). But he wasn't as lucky as me, he didn't have a dad with an engineer friend, he failed the finals while I was a couple of points away from an A.

So, to spell out the difference for you, since you seem to not understand it--the format in which the student is tested for proficiency in mathematics is distinct from the knowledge of concepts and skills required for mastery.
And yes, the grandparent post is correct. Any scientist or engineer should be able to demonstrate proficiency with these basic mathematical concepts (arithmetic, estimation, decimal numbers, rates, the Cartesian coordinate system, basic probability). In fact, I would say that ANY adult who has graduated high school should know how to do these things, for what would have been the point of attending high school in the first place if one so easily forgets such things?
Here's the thing. We can debate at length about the utility of such knowledge for the vast majority of people in this world who would presumably not need to know how to do math to succeed or even get by in their day-to-day existence. But why is it that this is the measure by which we determine whether something is worthwhile to know and understand? If that's the way we begin the conversation--i.e., "will I ever need to use this?"--then we've already lost the fight to educate subsequent generations. It's a regressive, know-nothing, anti-intellectual attitude that fails to appreciate the value of knowledge for its own sake. It's why American society is so troubled--large segments of the American public have lost the ability to think critically, having become too accustomed to the notion that someone else will do the analysis for them.

Educational psychology might (and definitely should) have included basic statistics, but it might not have, and depending on the way the course was taught, might have been easy to skate through.
