Document Summary
Review on mediating vs. moderating base hypothesis: a causes c. Mediating: a causes b and b causes c. Moderating: a causes c under conditions od d a is less likely to cause c under conditions of not d . it"s influencing the basic relationship. Sometimes a causes c but sometimes a is less likely to cause c. the condition d is therefore a moderator. Participants were advised that they would be randomly assigned to one of the two intervention groups (in the methods section): goal group, control group. Manipulation of the independent variable and random assignment. This ensures that all biases are canceled out. Now you have the two identical groups and then you manipulate the independent variable. University transcripts were collected for al participants for the semester immediately prior to and immediately following the intervention . Approximately 16 weeks afterwards all the participants completed the concluding questionnaire : negative emotions, enthusiasm.
