Fatima is using matched samples technique by ensuring that all children in her study have received identical amounts of supervision, thus attempting to control for the variable of supervision level. This method aims to make the groups as similar as possible except for the variable being studied (ice cream consumption and aggressive behavior), minimizing the impact of the third variable (supervision).
