Mediator – Moderator Using PLS-SEM

Mediator – Moderator Using PLS-SEM; WarpPLS 6.0 and SmartPLS 3.2.7 software Packages

Many studies in management, psychology, social science, including hospitality and tourism rely on mediating and moderating variables. Mediating variables are behavioral, psychological, or social constructs that transmit the effect of one variable to another variable. Mediation is one way that a researcher can explain the process or mechanism by which one variable affects another. However, moderating variable is those which affect the strength or nature of the relationship between two other variables. This session aims to explain the concepts and theories behind mediator and moderator and describes various forms of simple and complex mediators, moderators. Different methods to assess mediators and moderators will be discussed in this session. These assessments will be conducted in the context of partial least squares- structural equation modeling (PLS-SEM) using two powerful software packages namely; WarpPLS 6.0 and SmartPLS 3.2.7.
