Document Summary

Observe and systematically record behaviour occurring naturally in a natural setting. Strengths: study behaviour in natural context, results easy to disseminate. Limitations: certain behaviours difficult to observe, participant reactivity, subjectivity of researcher, uncontrolled settings, does not allow prediction and explanation. Correlation coefficient: a statistical technique that assesses how well you can predict one variable from another. The sign + or indicates the direction of the relationship. Strengths: can study real-world factors that cannot be manipulated in a laboratory, can collec. Limitations: correlation does not equal causation, correlational method tells us only that two variables are related, social psychology"s goal is to identify causes of social behaviour. Most often given to groups of people. Strengths: can have many participants, can collect information on many variables. Limitations: question effects, samples often not representative of population, responses not always truthful. Question effects: how a question is worded affects responses. Random sampling ensures it is representative of the population.
