<p>ace550,</p>
<p>Well the first reason might have to do with the fact that the surveys you posted ranked schools based upon their graduate business schools, while the BW survey that indy88 posted was for undergraduate business schools.</p>
<p>(Note that the 2004 BW survey listed includes schools such as Northwestern, Chicago, UCLA, Stanford, Dartmouth and Columbia–all which have only graduate business schools, not undergraduate business schools.)</p>
