Question

technique of observation​

Answer 1

Answer:

Observational research is a method of data collection that has become associated with qualitative research. [1] Compared with quantitative research and experimental research, observational research tends to be less reliable but often more valid[citation needed]. The main advantage of observational research is flexibility. The researchers can change their approach as needed. Observational research measures behavior directly, rather than the subject's self-reports of behavior or intentions. The main disadvantage is it is limited to behavioral variables. It cannot be used to study cognitive or affective variables.
