Abstrak
Data analysis of classroom action research (CAR) is conducted with three phases, namely: data reduction, data description, data conclusion. Data reduction is simplified process done through selection, focus, and raw abstraction. The description is a process of data performance in the types of narration, tables and graphs where the students are able easily to read. The conclusion stated is to determine the core of well organized data presentation in the brief, clear formulation. Data analysis on the CAR could be conducted with either quantitative or qualitative analysis and could be mixed between them.
