Harris Interactive derives its rankings by surveying U.S. consumers ages 15 and older online. The 2013 awards are based on a sample of 38,814 consumers, who were selected randomly from a Harris Interactive database of more than a million "cooperative residents."
Each respondent was asked to rate 40 randomly selected brands, Harris Interactive said, considering elements like familiarity, quality and purchase consideration.
Each brand received approximately 1,000 ratings.
Data were weighted to be representative of the entire U.S. population of consumers ages 15 and over based on age by sex, education, race/ethnicity, region, income. Data from respondents ages 18 and over were also weighted for their propensity to be online.
This is the same weighting approach Harris uses calling elections.
