*ROT
ROT
Rotates the answer options in a fixed sequential pattern across respondents. Each respondent sees the options starting from a different position, reducing order bias.
Usage Example
script definition (.q)
*QUESTION Q1 *SR *ROT Q1. Which brand do you use most often? 1:Brand A 2:Brand B 3:Brand C 4:Brand D
Rotation follows a deterministic sequence based on respondent order, unlike *RANDOM which is fully random.
Works with *SR, *MR, and *RANK question types.
