Hello everyone,
I would like to ask some questions about appropriate statistical test for our study design.
This study aims to evaluate the postural balance among parkinsonian patients.
We have 3 groups, and in each group we have 4 – 4 – 3 subjects, randomly attributed, and 3 different interventions for each group.
We perform a pre-evaluation and a post evaluation after 6 weeks of intervention.
We have severals dependant variables.
As Laerd statistics advise us with the statistical selector we used a Two-way mixed Anova. We have some concern about our statistical power due to the small sample size in each group.
We would like to see group differences, but also if possible, associations & correlation. Is a Two-Way Mixed Anova the right test or Linear Regression is a better one ? Or neither ?
Thank you everyone
