Delete the duplicate age and gender questions
Delete the questions asking for respondent's zip code and last 4 telephone number digits
Add the following adjective differential to “Please rate the gluten claim on the label using the following scales: “confusing versus clear”
Add the OMB number and expiration date
Also, I added the following two sentences to A2 and B1 of the
Supporting Statement:
“The agency does not intend to
generate nationally representative results or precise estimates of
population parameters. The studies will use convenience samples
rather than probability samples.
