Research Methods
1. Survey Method: a set of questions is given to determine people’s attitudes, beliefs, behaviours
Advantages:
-reaching out to a large group of people in and efficient and cheap way
-anonymous
Disadvantages:
-response bias (can be a problem)
-misinterpretation word choice might confuse people causing them to answer differently. Ex. (gay
and gay)
-honesty
In order to generalize from your sample to the population, the sample must be
representative(unbiased) of the population
Random sampling: each person in the population has an equal chance of ending up in the sample
2. Naturalistic observation: use this method when you want to measure or describe behaviour as
people behave naturally in a natural setting
Advantage:
-people are behaving naturally

Document Summary

Research methods: survey method: a set of questions is given to determine people"s attitudes, beliefs, behaviours. Reaching out to a large group of people in and efficient and cheap way. Misinterpretation word choice might confuse people causing them to answer differently. In order to generalize from your sample to the population, the sample must be representative(unbiased) of the population. Random sampling: each person in the population has an equal chance of ending up in the sample: naturalistic observation: use this method when you want to measure or describe behaviour as people behave naturally in a natural setting. Participant observer (recording and participating with group) You cannot infer cause and effect, can"t interpret behaviour. Expectancy effects or experimenter bias: observer records things they expect results will be bias. One way to help overcome experimenter bias is: have more than one observer helps determine inter- observer reliability (consistency: the experimental method (experiment):
