Quizplus · Accepted Answer

A laboratory observation would allow Professor Kribs to directly observe and measure the responses of infants of different ages when left with a stranger. This approach would provide the most controlled and precise data for her study. A single-blind or double-blind experiment would not be suitable as they typically involve manipulating independent variables, which is not necessary for this study. A survey would also not be practical as infants are not capable of completing surveys.
