$\begingroup$ This could do with a less technical / more layman's explanation. I've taken a few statistics courses and I've done PCA and I still can't understand much of the explanation. What are the eigenvectors/values? I know what variance is, but what does it mean for a direction to have high variance? And why do we care about that? $\endgroup$
