Fundamental statistics * in psychology and education (6th ed.). * Getting back to normalization, we have illustrated this syntax * with an example from the classic: * Guilford, J. * This is also a linear transformation and the resulting scores (C) * are often known as converted scores. * You can also change the mean and the sd of standard scores * by calculating C = z*sd + mean. * Note that the standardization doesn't change the shape of the * original distribution. * You can do this in SPSS either by using the menus (DESCRIPTIVES…/Save * standardized values as variables) or by the simple syntax: * DESCRIPTIVES VARIABLES = VAR1 (ZVAR1).
* To find a standard score, just calculate z = (X – mean)/sd. * Standardization is a simple linear transformation of raw scores, * so that the new distribution will have a mean of 1 and a sd of 0. We can do this by taking the cumulative * proportions of raw scores as probabilities, finding their * corresponding normal deviates, and converting them to normalized * scores with a desired mean and standard deviation. * Normalization is a kind of nonlinear transformation (area * conversion) of scores, so that the new distribution may have a * normal or bell shape.
