Because they really like having a population who, even if they remember the difference between mean and median and why these can be flawed ways to measure things, don’t really have the time in between just surviving on shitty wages and crap job security and rising costs of living and lack of social support mechanisms to get all critical and cynical about blatant political lies.
(A competent media could help them out on that, but none have been seen in the wild in this region for years and the species is now feared to be on the point of extinction.)
Still, props to Bright Red for this guest post at The Standard laying out why our Minister of Finance is either amazingly incompetent or feels very secure in the knowledge that he simply will not be called on this shit.
Our teacher had 10 of us line up at the front of the class and measured our heights. From that she calculated an average.
Then, she got the tallest boy to stand on a chair and measured his height again. He was now 50cm higher. The average of the ten kids went up 5cm. But nearly all of were the same height.
That was the first lesson: average does not mean typical, it can be influenced by movements in outliers.
Though I always like the “kill two rhetorical birds with one stone” method of getting 6 people in a room, working out a rough average wage for them and then saying “Oh look, here comes the CEO of Telecom! Now you all have a mean wage of $1 million a year so you must have no financial worries!”
