Успеваемость среди школьников за последние 30 лет вряд ли улучшилась, поэтому даже если и были допущены в этом плане методологические просчёты при проведении исследования, то они сильно картину не изменили.
Cato is very good at producing nice, thought stimulating, or at the very least very funny cartoons. Unfortunately, as a thumb rule their data are routinely doctored and/or misrepresented and can not and should not be trusted.
How about a source? Cato is criticised for playing with climate change skeptics and for sponsorship by successful industries, but by whom are they charged with manipulating data?
Hmmmmm.. Let's see... There are many others, but how about... myself? A person I really trust, you know. Cato has its ecological niche and plays its important role in questioning everyone and everything. However, they are agenda-driven, they are manipulative, their reasoning is biased and lacks logic, and their numbers are either outright wrong or misrepresented/taken out of the context. Do not take me wrong, they are not the only politically motivated entity of this sort, but this does not make me trust them any more than those others. Just an opinion based on review of some of their captivating essays. Not really interested in digging through others.
It is one thing to (ab)use data to make a point or advertise or publish in a scientific journal . . . and it is quite another transgression altogether to report fabricated or bad data. For the second time I ask, can you provide an example of "outright wrong" numbers published by the Cato Institute?
на сколько 10% менялись test scores по отношению к 1970 году В предположении, что либо существует один и тот же экзамен, который все писали последние 40 лет, либо существует какой-то способ переводить результаты одного экзамена в другой. На самом деле, ни то, ни другое предположение не верно, но это мелочи :)
