I'll read the name of a person and I'd like you to rate that person using something we call the feeling thermometer. Ratings between 50 degrees and 100 degrees mean that you feel favorable and warm toward the person. Ratings between 0 and 50 degrees mean that you don't feel favorable toward the person and that you don't care too much for that person. You would rate the person at the 50 degree mark if you don't feel particularly warm or cold toward the person. If we come to a person whose name you don't recognize, you don't need to rate the person. Just tell me and we'll move on to the next one.Gender Bar Chart050100150200250300350400450500550600650700750Male FemaleGender Pie ChartMale47%Female53%Basic Graphical Summaries 9/4/20063Marital Status Bar Chart0100200300400500600700Married Widowed Divorced Separated NeverMarriedPartneredMarital Status Pie ChartMarried51%Widowed8%Divorced13%Separated3%Never Married23%Partnered2%Marital Status B/W Pie ChartMarried51%Widowed8%Divorced13%Separated3%Never Married23%Partnered2%Basic Graphical Summaries 9/4/20064Marital Status Exploded Pie ChartMarried51%Widowed8%Divorced13%Separated3%Never Married23%Partnered2%Back-to-Back Stemplot*2 0-255544443 3-5 458776666-866777778888881000999-1190001114212-14 22234Daubert States (23) non-Daubert States (27)Histogram-Age0 20 40 60 80 100Freq uency18 22 26 30 34 38 42 46 50 54 58 62 66 70 74 78 82 86 90AgeBasic Graphical Summaries 9/4/20065Histogram-Age0 5 10 15 20Percent18 28 38 48 58 68 78 88 98AgeHistogram-Party ID0 50 100 150 200Frequencystr demdemind demindind reprepstr repj1x. summary: r party idTime Plot-Independents0%2%4%6%8%10%12%14%16%1950 1954 1958 1962 1966 1970 1974 1978 1982 1986 1990 1994 1998 2002
