Comments on: Stat 101 https://zuschlogin.com/?p=78 Human factors, human-computer interface, GUI design, and usability engineering pondered monthly by Michael Zuschlag Thu, 24 May 2012 13:11:51 -0700 http://wordpress.org/?v=2.8.6 hourly 1 By: Michael Freeman https://zuschlogin.com/?p=78&cpage=1#comment-1977 Michael Freeman Thu, 08 Jul 2010 11:44:29 +0000 https://zuschlogin.com/?p=78#comment-1977 I would really like to see another post discussing regression testing for significant factors. For example, before a change to a site we had a bounce rate of X% and now after the change we have a bounce rate of Y% (actually the daily rates fluctuate with some overlap). The goal is to see whether the change actually is having a real effect on the bounce rate or if it is just random.

I only use numbers in my work to substantiate the validity of my findings. What I would love is to find an easy way to use number as part of my analysis. You seem to have given a whole lot of thought to how numbers can not just substantiate but reveal new findings in user experience work. The problem is my mind "switched off" around the point you started using decimal points..(: Do you think you could post a follow-up to this post, targeted at people like me, who would love to use numbers in their work but in a fashion that is simpler to understand and execute?

People get so hung up in arguing the hard-core theoretical side that they forget the point of why we do these things. There's a balance between rigor and progress.

I have the same problems when I present the user tests data. Project managers don't know much about statistics, but enought to argue the validity of your findings. I would ask for your permission to traslate it into spanish. Regards, Olga Hi,
