Data file column descriptions:
Vignette read: Represents which vignette the participant read.
1 = John has chronic back pain vignette
2 = John has major depressive disorder vignette
3 = John has PTSD vignette
Total Score: the total score the participant got on the Social Distance scale
Instructions:
Open the data file in JASP.
label the vignette conditions in the header for the column (1 = back pain, 2 = major depression, 3 = PTSD)
Run a one-way ANOVA on total score, using Vignette read as the Fixed Factor.
Conduct a post-hoc test between the different conditions
Get descriptive statistics on the data and create a graph of the data
