Description |
This chapter describes the data management procedures used by the SACMEQ study, in which data have been collected from many thousands of pupils sampled from complex target populations in association with different educational systems in Southern Africa. Furthermore, data have been collected at different “levels“ (i.e., pupils, teachers, schools) and have been merged, aggregated, disaggregated, etc. prior to the main data analysis. The discussion will therefore focus on the main steps in data management that were required for SACMEQ to take in order to ensure that the quality of collected data is adequate, that data are turned into useful information, and that the more common data management problems are avoided. |
