Matching is a procedure whereby pairs of subjects are matched on the basis of their similarities on one or more variables, and one member of the pair is assigned to the experimental group and the other to the control group.
Matching is based on variables that we presume may have an effect on the dependent variable.

Dear MEL professionals, would you please help me out with the odd data? For example, in a survey about low-income parents, the column of age has some strange values, such as 120.

Hi, I realized that it seems the concept “outcome” is different from the term “output”. Taking the grandparent training project as an example, what is the “outcome’ referable?
