With a two-group design, there are different levels of treatments, which would be the experimental group and the control group (Myers & Hansen, 2012).
For my example I chose to write about how much a person drinks alcohol daily and their anxiety level as well as exercising level.
DV: Alcohol amount
IV: Drinks alcohol
· Level 1: Control group = No alcohol
· Level 2: Experimental group = Drinks alcohol
IV1: Anxiety
· Level 1: Low
· Level 2: Moderate
· Level 3: High
IV2: Exercising amount
· Level 1: 1x a week
· Level 2: every other day
· Level 3: Every day
