2. make a list of behaviours or categories that could be neaseured as aggressive
3.  decide on the sample being studied (what tv prog or adverts? what time of day?)
4. Tall (count) the times aggression occured 
5. Assess the reliabilty of their results

SAMPLING
good content analysis depends on looking at a good sample of programmes, books etc, time of day or type of programe which could lead to a BIASED sample.
