Abstract
This paper presents a study of mediation analysis (with one moderator variable) and the role of this variable in moving the effect from the independent variable to the dependent variable. In this article, the delta method was used to estimate the standard error. Because this method violates some assumptions, especially with small sample sizes, the bootstrapping method was used to overcome such problems. According to the results obtained from the application of this model, the method of bootstrapping is better than the Delta method based on the results.
