Question

Discuss the strengths and weaknesses of observational data collection. Identify either a strength of observational data methods (and how this contrasts with a weakness of survey methods) or a weakness of observational data methods (and how this contrasts with a strength of survey methods).

Answer 1

A primary advantage of observational study is that observations can be made in real life situations which allows the researcher to study people behaving naturally. This may not be the case in a survey as people are not always willing or share their own views or are influenced by biases while responding. In addition, observations provide more holistic data as researchers can access to the context and meaning surrounding what people say and do.
However, there are also some challenges associated with this method. Because researchers are usually immersed in a situation or culture during observations, their report can be highly subjective. In contrast, the survey method involves a simplistic collection of information that is not greatly influenced by the researcher. Futhermore, observations can be highly time consuming and costly, sometimes spanning over years together.
