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.
