Young people in the East Midlands were the most down-to-earth of those surveyed, expecting an annual salary of £33,468 by the time they reached their mid-thirties. However, even this figure is still around £4,000 higher than the average.
Two-thirds of respondents also thought they would own a house by the time they were 25. In reality, only 14% of homeowners are aged 25 or under.
With the rising cost of higher education hitting students hard, recent figures suggest young people will be left with more than £20,000 of debt by the end of their courses. But the poll shows today’s school children do not realise how out of pocket they will actually be: the average expected figure was just half the reality.
But the fact that the bell-curve lies flat in the plane confused my students no end. So I wasted half a day on creating a nice 3d-plot for them. After trying several options, I settled on pgfplots.sty, which builds on tikz/pgf, the comprehensive, portable graphics package designed by Tantau (here’s a gallery with most amazing examples of what you can do with this little gem). Plotting data and functions with pgfplots in 2d or 3d is a snap, so that was not too hard. Eventually.
