Internet click-throughs
A common theme throughout this course has been the nestedness of data. During this case study, you will examine the number of users who click through on a link to a website before and after a redesign. These users are nested within trial groups. You will then examine the outputs and make a recommendation to your client.
For this redesign, you will examine the web behavior of 10 people from 4 different focus groups, for a total of 40 people. You want to know if the number of clicks to different pages changed from the old to the new webpage while correcting for groups.
