Understanding
Correlation by Mark Holah
"A
really useful tutorial. The slides move simply and logically through all
you need to know about correlations with even a mention for inverted and
upright ‘U’s. Quizzes and animations check and reinforce the
ideas, I especially liked the moving scattergram very effectively demonstrating
a changing correlation coefficient. I will certainly be using this to help
my class teaching, individual students to make up missed lessons and for
revision. A word of warning - watch out for the spiders!! "
Frances Harding, principal examiner for one of the exam boards.
