- What is the z-value of the bootstrap mediation test?
- The Bootstrap mediation test z-value is used to evaluate the mediating effect of X on Y through M. The z-value is calculated as the mean value of the c' path divided by its standard deviation. The larger its absolute value, the higher the statistical significance of the mediation effect. The z value >1.96 indicates that the mediation effect is significant at the 0.05 level, the z value >2.58 indicates that it is significant at the 0.01 level, and the z value <-1.96 indicates that it is not significant at the 0.05 level.
