Representativa dos votantes da área em estudo, elaborada em três estágios. No primeiro estágio fez-se um sorteio probabilístico dos municípios pesquisados, pelo método PPT (probabilidade Proporcional ao Tamanho), com base na população de votantes (TSE 2014, excluindo abstenção 1º turno 2006 e 2010) de cada município. Em um segundo estágio, dentro dos municípios sorteados foram selecionados, também pelo método PPT, os locais de votação com base no número de votantes de cada local de votação. No terceiro estágio, dentro dos locais de votação sorteados, os respondentes foram selecionados através de quotas amostrais, proporcionais em função de variáveis significativas, a saber: Sexo, Idade, de acordo com o perfil dos votantes. Serão realizadas no total 64.200 entrevistas em todo o Brasil das quais 12.000 na região Sul, 19.300 na região Sudeste, 7.300 na região Centro-Oeste, 21.200 na região Nordeste e 4.400 na região Norte. Das entrevistas previstas na região Sul, 5.000 serão realizadas no Estado do Paraná, 5.000 no Rio Grande do Sul e 2.000 no Estado de Santa Catarina. A distribuição das entrevistas da região Sudeste considera a realização de 7.300 entrevistas no Estado de São Paulo, 6.000 em Minas Gerais, 5.000 no Estado do Rio de Janeiro e 1.000 no Espírito Santo. No Centro-Oeste serão realizadas 4.000 no Distrito Federal, 1.500 em Goiás, 1.000 no Mato Grosso e 800 no Estado do Mato Grosso do Sul. Na região Nordeste serão feitas 5.000 entrevistas no Estado da Bahia, 5.000 em Pernambuco, 4.000 no Ceará, 2.000 no Maranhão, 1.400 na Paraíba, 1.000 em Alagoas, 1.000 no Piauí, 1.000 no Rio Grande do Norte e 800 no Estado de Sergipe. Já na região Norte serão distribuídas 1.600 entrevistas no Pará, 1.000 no Amazonas, 600 no Estado do Tocantins, 400 em Rondônia, 300 no Acre, 300 no Amapá e 200 em Roraima. Para restabelecer o peso de cada estado no Brasil, os resultados serão ponderados. Considerando os Estados da região Sul do País, será utilizado fator 0,7 para o Paraná, 0,8 para o Rio Grande do Sul e 1,1 para Santa Catarina. Na Região Sudeste o fator de ponderação será de 2,0 para Estado de São Paulo, de 1,1 para Minas Gerais, de 1,1 para o Estado do Rio de Janeiro e de 1,2 no Espírito Santo. No Centro-Oeste, o fator do Distrito Federal será 0,2, de Goiás 1,3, no Mato Grosso 1,0 e no Estado do Mato Grosso do Sul também 1,0. Na região Nordeste, o fator de ponderação para o Estado da Bahia será de 0,9, em Pernambuco de 0,6, no Ceará de 0,7, no Maranhão 1,0, na Paraíba de 0,9, em Alagoas de 0,9, no Piauí 1,0, no Rio Grande do Norte 1,1 e 0,8 no Estado de Sergipe. Em relação aos fatores da região Norte, será de 1,4 no Pará, de 1,0 no Amazonas, 0,7 no Estado do Tocantins, 1,2 em Rondônia, 0,7 no Acre, 0,7 no Amapá e 0,7 em Roraima. A margem de erro máxima estimada para os votos válidos da pesquisa, considerando-se um intervalo de confiança de 99% e tendo como base o número de votos brancos e nulos da eleição de 2010 é de 2(dois) pontos percentuais para mais ou para menos sobre os resultados encontrados no total da amostra. A margem de erro é apresentada sem casa decimal da mesma forma que os resultados são apresentados, ou seja, sem casa decimal.
