The main purpose of matching is to reduce initial differences between the experimental and control groups on the dependent variable. Matching can be done based on various factors such as age, gender, socioeconomic status, etc. This helps to create two groups that are as similar as possible and helps to ensure that any observed differences between the groups are due to the treatment being tested and not some other factor.
