Moreo about Observational research:
In observational research, people and phenomena are observed in their most natural environments. Instead of using organised environments like study labs or focus groups, this allows researchers to observe how their participants make decisions and respond to circumstances in their everyday lives.
The study of non-experimental circumstances in which behaviour is observed and noted is referred to as observational research. The phrase "what really is going on or what's he doing" could also be used. The variables are neither controlled nor manipulated, hence the study is categorised as non-experimental.
