In many scientific communications, we are confronted with data showing "no statistically significant difference" between two groups (populations) with respect to a certain variable. The authors often conclude that the two groups are not different regarding that variable. Such a conclusion is not warranted without an indication of thepowerof the statistical test to detect aclinically important difference. In reality, the two groups referred to almost certainly are at least minutely different. However, whether or not the difference will lead to a statistically significant difference between samples in the study depends on the following: (1) the variability of the variable in the population (which can be estimated using the standard deviation of the same or similar data), (2) the sample size (the number of independent subjects or data points in the samples from each group), and (3) the chosen level of significance (the probability that any difference found

Abstract Chapter 2 reviews the philosophies, concepts and discourses that underpin provision and form the basis for the evaluation of its impact. Discourses are situated in particular social and political settings and so the chapter begins with a discussion of the nature of post-modern societies with an emphasis on diversity, identity and lifestyle. The focus then shifts to the discourses that have shaped supported housing. Most emphasis here is placed on the discourse of well-being which forms the basis of the evaluation framework used in the book. The history of the well-being discourse is described and the underlying rationales for the discourse assessed. It is argued that the discourse is of most use if the psychological concepts that underpin it are uncovered and operationalized. The main concepts of personal control, identity and self-esteem and social relations are described and applied to the situation of supported housing. The final part of the chapter examines the way that the discourses and concepts have been used to assess the outcomes of supported housing, either through inspection by regulatory agencies or through performance measurement regimes.
