Abstract

It has become an important means of empirical research for obtaining research data through random experiments. Due to the human interference factors and the complex and changeable social psychological phenomena, it is significant to improve experimental validity. In statistics teaching, randomization and repeatability are the basic principles to be followed in randomized experiments. Correcting experimenter bias and participant bias are two important aspects to improve internal validity. Selecting sampling groups randomly and reducing demand characteristics are effective strategies to improve external validity.
