Average hourly wages for large retailers. How accurate are they??

I have not worked retail in quite some time. I would appreciate anyone seeing this and have worked for any of these companies (or in similar one) confirming these numbers are about right or if they are high or low. From the source, it seems these are "average hourly wages", so new-hires to experienced workers wages are included. Just curious as to how accurate these are. Thanks!
