Mediating effect refers when a third variable intervenes between the related constructs and explains why a relationship between them exists (Hair et al., 2009). There are several types of tests that can test the mediating effects. McKinnon, Lockwood, Hoffman, West, & Sheets’ (2002) summary of the tests of significance of intervening variable effects is shown in Table 1.
In addition to the methods displayed in the summary table, recently other methods such as Bootstrapping (e.g., Bollen & Stine, 1990) and the Monte Carlo Method (e.g., MacKinnon, Lockwood, & Williams, 2004) have become popular. Bootstrapping is a non-parametric method based on resampling with replacement that is performed many times (e.g., 1000 times). From each sample, the indirect effects are computed and their distribution is generated. The Monte Carlo Method is a computer simulation test of the indirect effect that is proposed by MacKinnon et al. (2004).
Baron and Kenny (1986) provided a seminal work in their assertion of specific steps for testing cross-section mediation models. They provided four conditions or steps for testing in their causal steps approach, which linearly lays out specific relationships amongst the independent, dependent, and mediator variable in four separate regression models. These four steps are noted below:
1) Demonstrate that the independent variable (X) is significantly related to the dependent variable (Y). This is denoted as the c path.
2) Demonstrate that the independent

Women’s roles in society have become more equal to men’s and have overwhelmingly changed since the 1930s. There have always been influential women throughout history, however, their influential techniques have changed greatly. In the novel To Kill A Mockingbird by Harper Lee, women’s expectations, roles and opportunities, and their treatment can be compared to women today.

Bootstrapped mediation analyses (Preacher & Hayes, 2008) were performed to examine how self-worth would mediate the association between prosocial behavior and overall happiness. A total of 5000 bootstrap resamples were used. The analyses revealed that self-worth partially mediated the association between prosocial behavior and overall happiness, ab = 0.04, SE = 0.01, 95% CI [0.03, 0.06]. Although the total effect of prosocial behavior was significant, c = 0.15, SE = 0.03, t(1098) = 5.17, p < 0.001, its direct effect was mediated by self-worth, c’ = 0.11, SE = 0.03, t(1098) = 3.87, p = 0.001. See Figure 1 for a depiction of the mediation model.
al.,2007). Using previously researched scholar articles and books, the authors were able to base their search, follow certain guidelines and compare their results with other results. Using tests such as the Kruskall-Wallis non-parametric test, Nagel et. al.(2007) were able to examine the differences in performance based on each grade group.
The studies are varied and numerous. To provide examples of these surveys I would like
The practice of settling human conflicts through intermediaries has had a rich history in Western and non-Western cultures and therefore a broad range of forms and functions. The conflicting parties in most of the societies and at all stages of social interaction have had access to external actors to whom they approach when they come to the conclusion that they are incapable to handle their different opinions by themselves. In this case, an ordinary response to identify contradictions in objectives and values be-tween adversaries is to enter into a process of negotiation in order to achieve an agreement on such differences, which is mutually acceptable. In consequence, negoti-ation seems to be a universal, human
To what extent is the relationship between China’s economic prosperity and its population’s quality of life a positive one?
The objective of this chapter is to describe the procedures used in the analysis of the data and present the main findings. It also presents the different tests performed to help choose the appropriate model for the study. The chapter concludes by providing thorough statistical interpretation of the findings.
