A student working on his MSc thesis uses an experimental design to test if people that watched a negative piece of news give a lower evaluation of the image of a specific company than people that watched a neutral piece of news. The evaluation is measured on a scale of 1 (extremely negative) to 5 (extremely positive).
The data give the following results:
| Experimental group (group 1) | Control group (group 2) |
| n = 60 | n = 60 |
| Mean = 3.40 | Mean = 3.60 |
| SD = 0.60 | SD = 0.60 |
Transform the data given above into a regression equation. The dependent variable (Y) is the evaluation of the image (EVALUATION) and the dependent variable (X) is the group (GROUP), where the control group is the reference category (control group = 0, experimental group = 1).
