Best training for Statistical Software?

<p>Does anyone have any recommendations for beginners level training or certifications in SPSS, STATA, SAS or any of the other statistical software programs?</p>

<p>I'd prefer to take these without having to sign up in a tuition granting program. </p>

<p>I checked out IBM SPSS on a website but I'm curious as to how credible this is in academia and the professional world. </p>

<p>Any advice would be appreciated. Thanks</p>
