Here is something I have learned this week: systematic variance is the deviation of the group means from the grand mean and an F test is a ratio of systemic variance to error variance. You're welcome.
Other things: it is easier to write fast with a fountain pen. When you feel like you can't stuff any more information into your brain, time for purple jet planes and black coffee.
I have been swotting for my first university exam in 20 years - and couldn't peel the potatoes afterwards. Writing in longhand rather than desultorily resting one's wrists on a keyboard is hard work. But that's not the hardest thing. The learning of facts by rote makes me feel like a muggins.
I am 45, I've had a career, this week I got voted on to my kids' school board, surely I'm missing some smart, quick method of learning all this guff without having to sit for hours and hours taking notes? What do you mean, there is no minion pig to do the gruntwork for me? There must be some trick to pass this paper without the tedious hours and hours of memorising types of criterion-orientated validity.
(Yes I know, I'm going to sling my yoga mat over my shoulder and talk about statistical equation modelling. Wanker.)
