Development of a Task Model for the Analysis and Retrieval of Statistical Data

Abstract

This chapter explores the task of retrieving and analysing statistical data from external sources, such as national statistical agencies, government departments, the World Bank, etc. Although external statistical data (ESD) is widely used in planning, decision-making and project evaluation, the process of gathering and analysing such data is poorly understood. This chapter describes the usability testing of a prototype Statistical Information System (SIS) and uses the data gathered during that testing to develop an initial task model for retrieving and analysing ESD. The proposed task model would be useful in the development of improved Statistical Information Systems, particularly those intended for use by casual or ad hoc users.
