Abstract: Examples disclosed herein to estimate volume of switching (VoS) among television programs include determining, based on panelist program viewing data, a first VoS value representing a portion of a decreased amount of tuning by matched panelists to a first program from first to second measurement periods to attribute to an increased amount of tuning by the matched panelists to a second program from the first to second measurement periods; estimating, based on the program viewing data and first VoS value, a second VoS value representing a portion of a decreased amount of tuning by unmatched panelists to the first program from the first to second measurement periods to attribute to an increased amount of tuning by the unmatched panelists to the second program from the first to second measurement periods; and combining the first and second VoS values to determine a third VoS value for a combination of the matched and unmatched panelists.

Abstract: Example program clustering methods disclosed herein include accessing person-level program viewing data representing lengths of time respective people in an audience have tuned to respective television programs to be clustered. Disclosed example methods also include determining adjusted person-level program viewing data for respective ones of the people having tuned to respective ones of the television programs. For example, first person-level program viewing data for a first person having tuned to a first program is adjusted based on a ratio characterizing a relationship between a first program rating associated with the first person having tuned to the first program and a first network rating associated with the first person having tuned to a first network associated with the first program.

Abstract: A vessel has an annular upstanding wall and a bottom that together define an inner shell adapted to hold a vessel media. A baffle system is disposed in an interior of the inner shell and comprises a plurality of baffle portions each being generally an elongate planar member with a length edge and a width edge, and a tab projecting from the length edge. Each of the baffle portions is mounted to the upstanding wall at their respective tab with one of the baffle portion above the second baffle portion and a space therebetween.
