Assignment Problem: Identify the errors in the following research report introduction: A study was conducted to evaluate a counselling program designed to reduce depression symptoms in a group of Australians. Participants were randomly assigned to one of two groups (youngeage group or an older age group). It was hypothesised that face-to-face counselling would be more effective at reducing depression than online counselling. It was also hypothesised that this difference in depression symptoms would be observed in older participants but not in younger participants. Figure provides a means plot for this scenario.
