SN:3764 British Social Attitudes survey, 1995 Please note that the data must be weighted in all analysis to take account of unequal selection probabilities. Slightly simplified, households are selected for the sample with equal probability, but only one person is interviewed in each household. Persons in large households therefore have a lower chance of being selected for interview than persons in small households. The weighting corrects for this. The file is not preweighted. In SPSS the following command can be used: WEIGHT BY WTFactor (or similar, depending on the exact syntax of the version of SPSS being used).
