Hello!
I would like to combine data of mothers and fathers (data on parenting stress) in one single parenting stress variable. Unfortunately I am limited to non-parametric methods as my data are non-normally distributed and the total amount of participants is 15 (of which 15 mothers and 14 fathers filled out the questionnaire). I already checked for differences between mother and father scores using a Wilcoxon signed rank test and found no statistically significant differences (I assume this is the correct procedure?).
What method do you suggest? If you need any additional information, please do not hesitate to ask!
Thank you very much.
