In addition to tasks that need revising, we may find that some of our survey questions didn’t quite hit the mark the first time around.

For example, we may have given participants a multiple-choice question that didn’t include the answers they needed, so we got a lot of “other” responses.

• example ss

In the next round of testing, we can revise our list of answers so that we can turn that big blob of “other” into more useful specifics:

• ss of revised answers

Again, by revising our questions between rounds, we lose some of our ability to compare the results against each other, but given the choice of analyzing two sets of cloudy data vs. 1 set of clear data, we’ll always take the latter.
