Answer:
Observational method/Field experiment
Explanation:
A field experiment is conducted on a daily bases. In this field experiment, the experimenter still manipulates the independent variables.
But this happened only in real-life settings. In this experiment, the experimenter was not in that condition to control the extraneous variables. This experiment can conduct real life.
Thus Terence mentor recommends the observational method/field experiment.
