Controlled observation is a type of observational study where thesituations areplanned by the researcher. This type of observation may be carried out in a laboratory type situation and because variables are manipulated is said to be high in control.
The weakness of the method is that it will be low in ecological validity compared to naturalistic observation. If participants are aware they are being studied they behave differently.

Systematic observation includes naturalistic observation, which is real-life observation, and structured observation, which takes place in a natural environment in which manipulation is involved
No, empirical evidence is based on observation and inference. Qualitative observation is an observation of the qualities of an object. Quantitative observation, on the other hand, is an observation based on some sort of numerical measurement of the object.
