Evaluation and impact measurement
Impact measurement using statistical methods
Typically, statistical or econometric methods are used for the evaluation of effects of public measures when a large amount of quantitative data is available, e.g. register data and questionnaire data. An advantage of statistical or econometric methods is that it is possible in the analysis to take into account a series of other important issues. It is therefore possible to a large extent to "isolate" the connection you are interested in analysing. Using more advanced methods, and when observations of the same individuals exist for many years it is also possible to take into account the importance of unobserved factors.
Evaluation using qualitative methods
Qualitative methods are generally understood as data collected and interpreted in ways allowing the results to be presented in a non-numerical form. AKF has, among other things, evaluated energy-saving activities, social-security offices and efforts towards the homeless, the mentally ill and abusers using qualitative methods.
Qualitative methods are especially suitable when the problems are about the understanding of people's attitudes and actions and when uncovering complex courses of action over time. Qualitative methods are often suitable for pointing out context dependent behaviour and for throwing light on complex mechanisms in causal processes. The qualitative methods could be necessary in order to uncover use of concepts and forms of action in connections unknown to the researcher.
