Very useful series on statistics. I wonder if covariances between subjects in a course of study have been calculated (to gauge the correlations of subjects) before the course is offered. And students get more information on what results they can expect by taking their course of study. It seems that our students just take whatever they can get instead of what really ‘fit’ for them. (We are wasting ‘potentials/opportunities’ by not fitting people to ‘jobs’ – in other words, not using ‘covariance’.)

(If more politicians would make use of statistics as bases for their policies!)
