Re: st: MANOVA to verify difference

[Damiano Bordogna <damiano.bordogna@gmail.com>]

Thank you Ronan,

i'll try to introduce you my problem!

My database is made of
- 57 observation (divided into 6 groups of respondant), representing
firm's stakeholders (iROWS)
- 11 binary variables, representing stakeholders' objectives (COL)
- 4 normal (not descrete) variables, representing stakeholders' salience (COL)

I want to verify if there are differences between the different groups
according to the choosed objectives (VERY IMPORTANT: as said before,
objectives are dummy variables, 0-1).

Thank you again Ronan!

All you can do is see how well the observed differences are explained by chance, and, more important, see if the observed effect sizes are of any real life importance.
