In my Intro survey I have an 18% branch – At first it seemed to be working at about the right pace. For the last few months it has been pulling more like less than 5% of the people? Any ideas?
SG’s documentation about the percent branch talks about the way it works (http://help.surveygizmo.com/help/article/link/branching-a-b-split-testing), I’m not sure if you’ve run across that. It looks like it’s not abnormal for the percentages to be off since the whole thing is completely random, like a coin flip. The way to increase the odds of the branching percentage being more of what you expect would be to receive more responses, if that’s a possibility for you.
