Data analysis and interpretation is a critical aspect of evidence-based policy decision making. Data collection is, therefore, not an end in itself, but a means to an end. In order for the collected data to be useful, it must be correctly processed, analysed and interpreted to inform evidence-based decision making. Socio-economic data analysis and interpretation involves an array of possible methods, tools and techniques with different areas of application. It is therefore important that planning and research officers be made familiar with the various techniques as well as processes of data analysis and interpretation. The need to build the capacities of planning officers in this area provides the rationale for this workshop.
