Document Summary

2: use the questionnaires to give the data context. 3: use the codebook to link the software with the questionnaires. 1: define the number of bins (level of aggregation) 2: restrict the width by specifying a range. Equal probability: bin width is different, separated by the chance of being in each bin as equal. Standard normal model: z = (y ) / . Standard deviation: used to measure dispersion of or variation in quantitative data that retains the unit of analysis. Z score: the distance from the mean in standard units, doesn"t change the shape of distribution, changes the centre by making the mean = 0, changes the spread by making the standard deviation.
