This is describing randomized matching, where subjects are paired before being randomly assigned to a group. Random assignment would be if subjects were simply assigned to a group randomly without any pairing beforehand. Homogeneous selection refers to selecting subjects who are similar on certain characteristics. Analysis of covariance involves adjusting for a pre-existing variable that may affect the dependent variable. Use of subjects as their own controls refers to a design where each subject serves as their own control in a study.
