# Data File Setup for Questions with Rotations or Randomization

Rotations and randomizations that occur between respondents within a question need to be removed from the data prior to creating the data file. Generally, this should be done in accordance with the questionnaire’s coding. For example, if the questionnaire said:

Q1	Which of these have you eaten in the past week? RANDOMIZE ORDER OF 1 AND 2

McDonald’s
Taco Bell
None of these


Then half the sample will have been asked:

Q1	Which of these have you eaten in the past week?
McDonald’s
Taco Bell
None of these


And the other half will have been asked:

Q1	Which of these have you eaten in the past week?
Taco Bell
McDonald’s
None of these


When the data is exported, it should be done using the order in the questionnaire. That is, even though Taco Bell was shown first half the time and second half the time, the data file should be created as if Taco Bell was always shown second.
