The document discusses various primary and secondary research methods that can be used for social research. It provides examples and advantages and disadvantages of two primary and two secondary research methods. For primary methods it discusses direct observation, where a researcher observes a group without becoming a member. Advantages include noting non-verbal cues and unexpected events, while disadvantages include potential personal bias and reactivity. It also discusses interviews which can provide additional insight but may not be as useful as direct observation. For secondary methods it discusses official statistics which can help form hypotheses and allow comparisons, but may be incomplete, inaccurate, or outdated. It also discusses mass media reports which can similarly help research but rely on other sources and may become outdated.
