Hi,

Kindly, I have two questions related to the multidimensional scale model:

1- Is there a minimum number of objects (product) I need to apply to use the Multidimensional Scale (2 dimensions, not 3)?

2- What is the best Likert scale option to apply for Multidimensional Scale (1-4) (1-5) or (1-7)? "considering that I'm trying to reduce the neutral answer option."

Thank you!
