Assume you wanted to investigate the length of time a team had played together (predictor variable) and the effect it had on the team's cohesion (outcome variable) with personality being the mediator variable. Which of the following best describes the direct relationship in this example?
If you were researching the effect of hours training and attitude on the performance of a specific skill (e.g. goals scored) how many possible predictors would exist in attempting to determine the relationship between the predictor variable (hours of training), moderator variable (attitude) and the outcome variable (performance)?
If you were investigating the moderator effect of attitude (i.e. positive or negative) and the relationship between hours training and performance, which of the following levels would be necessary to evaluate the interaction effects?
Assuming you were researching a positive attitude effect, how would you interpret the following result based on the relationship between training and performance? b = 0.511, 95% CI [0.191, 0.595], t = 3.98, p < .001
