thank you very much for your help, well first of all i going to try to write the most clear that i can (i'm not an anglo speaker) i'm learning english and mathematica.
I have this data base (this are not the real data) with answers of an perception scale (from A1 to A9), and i have another variables like gender, age etc. I would like to know how to compare all this vectors, for example all the means from A1 to A9, and if there more influenced by age or gender, i going to add the excel file.
I appreciate your help
