Knowledge Networks collects data using a probability-based panel designed to be statistically representative of the U.S. population. Households are selected randomly with a known probability of selection, allowing Knowledge Networks to provide a confidence interval for statistical estimates.
Knowledge Networks maintains its panel using the United States Postal Service's Delivery Sequence File, which allows the inclusion of households that are cell phone-only, which are often missed in standard sampling designs.
Selected households are invited to participate in Knowledge Networks's Web enabled panel. Those who agree to participate, but are not already on the Internet, are sent a laptop computer and receive an Internet service connection provided and paid for by Knowledge Networks. People who already have computers and Internet service are permitted to participate using their own equipment.
