ES3C: Please look at the ENERGY STAR label on the left. Have you ever seen or heard of this label? (Respondents were randomly shown either the old or new ENERGY STAR label. This question was asked to respondents who said they had not seen or heard of or didn’t know whether they had seen or heard of ENERGY STAR.)
ES3D: Have you seen or heard of this version of the ENERGY STAR label? (In this question, asked after ES3C, respondents were shown the label not shown in the previous question.)
ES6: Now that you had the opportunity to see the ENERGY STAR label, do you recall seeing or hearing anything about it before this survey? (This question was asked to respondents who answered “no” or “don’t know” to ES3A and ES3B. It was also asked to all respondents who answered ES3C and ES3D.)
Respondents who answered ES3A, ES3B, ES3C, ES3D, or ES6 “yes” were categorized as recognizing the ENERGY STAR label (aided).
Respondents who did not answer ES3A, ES3B, ES3C, or ES3D “yes” and answered ES6 “no,” were categorized as not recognizing the label (aided).
Respondents who did not answer ES3A, ES3B, ES3C, or ES3D “yes” and answered ES6 “don’t know” or refused to answer ES6 were not included in the analysis of aided recognition. (Their data were set to missing.)
