Add Median, Mode, and Mean calculation tool for surveys.
It would be great if there was a built in mean, median, and mode calculation tool in the survey system.

We are currently planning on adding an option to include a Media or a Mode to all applicable question types. We will review the idea of adding Median and the option to do calculations excluding those that did not answer the question.

I agree! Let me also add that the mean score needs an option to exclude questions that were unanswered or had a "not applicable" answer checked. One problem with surveygizmo's built-in scoring feature is that if a participant skips a question, it artificially lowers their score (i.e., it acts as if they'd entered a zero). This is a common problem in research studies, where we usually have to allow participants to skip questions if they want to. The proper solution is (usually) to divide the sum of their responses by the total number of answered questions. I just spent an hour writing a custom script to do that for one of our surveys, and having it as a built-in option would be very nice.
