You can if it's a computer picking the password from presumably common words. If the human is picking anything than there WILL be a bias in selection. Effort should be made at minimizing that, but even with education this is a difficult task for any worker. It got to the point where I actually took a classic literary work and made a 'password words' dictionary from it just so that I could have the computer generate possible new passwords. (there bias is mostly filtering out things that might be offensive... because someone can always take it the wrong way even if you explain in advance the theory of how the password was created by a computer).
