Hello everyone,
I need help with interaction effects in multiple regression analysis.
Study went like this: 120 participants solved 20 base-rate neglect tasks which all differed in ratio and congruence (mediators/moderators). They all solved statistical reasoning test (predictor). Correct response on base-rate neglect tasks were measured (criterion).
Predictor is statistical reasoning (score on statistical reasoning test), criterion is frequency of base-rate responses in base-rate neglect task (correct responses). Moderator (or mediator?) variables are the characteristics of base-rate neglect task (1. ratio and 2. congruence).
I have two questions:
1. Are ratio and congruence moderators or mediators?
2. How can I investigate the interaction effect of ratio and congruence of BRN task on the statistical reasoning-BR frequency relationship in Mplus or STATISTICA?
Thank you all
