Hello all,
I recently used a branching code posted on a previous thread. My aim is to branch two sets of questions, one question to 50% of the sample, and the other question to the remaining 50%.
We did a pretest of the form administering it to 19 people, the form contained two branching codes. With the first branching question module '0' was returned 6 out 19 times, while in the second branching question module 0 was returned 7 times. Both times module 1 was returned more times than module 0.
Is there a reason why module 1 is returned more often than module 0, and is there a way to ensure that both modules are returned an equal number of times?
The code I used in the end was:
once( concat(( round(random() * 100, 0) mod 2 ), " "))
I would really appreciate your help, many thanks in advance,
Henri
