Matching is a substitute for randomization in experiments。 true or false

False. Matching is not a substitute for randomization in experiments. Randomization is a crucial component of experimental design to ensure that the treatment and control groups are similar on average, and any differences observed between the groups can be attributed to the treatment. Matching, on the other hand, is a technique used to create similar groups by pairing or grouping participants based on certain characteristics or variables. While matching can help control for potential confounding variables, it does not replace the need for randomization in experiments.
