What is the difference between Positivism and Interpretivism?

Positivism and Interpretivism are both different sociological methodologies, mostly discussed with reference to research methods. When studying society, Positivists like to collect quantitative, objective data using surveys, structured interviews and official statistics. Positivists prefer using these methods because the data produced is quantifiable, it uncovers patterns of behaviour which can be analysed for patterns and trends. Interpretivists on the other hand, value qualitative data, which they prefer to collect through unstructured interviews, participant observation and documents. Interpretivists want to uncover the meanings held by individuals and social groups because they believe that each individual/group defines 'reality' differently. To understand these different definitions, interpretivist research therefore involves going to the groups and allowing them to act or speak openly.
