Background Memo  

The poll by Fairleigh Dickinson University's PublicMind was conducted by telephone from August 21 through August 27 using a statewide, randomly selected sample of 651 registered voters in New Jersey aged 18 and over. The sampling error for 651 adults is +/- 4 percentage points at the 95 percent level of confidence.  Survey results are also subject to non-sampling error. This kind of error, which cannot be measured, arises from a number of factors including, but not limited to, non-response (eligible individuals refusing to be interviewed), question wording, the order in which questions are asked, and variations among interviewers. All PublicMind interviews are conducted by TMR, Inc. of Cedar Knolls, NJ.  Professionally trained interviewers use a CATI (Computer Assisted Telephone Interviewing) system. Random selection is achieved through computerized random-digit dialing. This technique gives every person with a phone number (including those with unlisted numbers) an equal chance of being selected. 

The questions were as follows:

Question:  Have you heard of [rotate list]? If you haven't just tell me. [If yes, ask:] Do you have a favorable or unfavorable opinion of …? Would that be very or somewhat?
