I have become interested in statistics, but I must admit that it has been a long time since I have used math seriously. Sometimes I understand what equations mean, but sometimes I can't follow them.
I like the answer given here that uses the image with an arrow: Conceptual understanding of root mean squared error and mean bias deviation.
Would you have any advice regarding serious statistical books on modeling, PCA, simulation, etc., that use figures more than equations? I'm hoping for something like a 'stats for dummies' book, a book that would make stats accessible for everyone?.
