Analyses of memory knowledge as a function of demographic measures for public sample respondents.

The percentages for sex, race, and age (older/younger than 50) resulting from the weighting process are matched to U.S. Census values. After weighting the nominal sample size is 1500 respondents. The percentages for education, income, number of psychology books read, and number of psychology classes taken were measured but not used to determine sampling weights. Note that some subjects declined to answer the income question (4.4%) and the education question (0.07%).
