I have 3 dependent variables (DV) and 2 independent variables (IV) where 1st IV have 3 sub categories and 2nd IV have 2 sub categories. I need to compare the means.
You can compare the means of your dependent variables by using t-tests and conclude significant difference or the lack of significant difference.
If you have enough data, you can find correlation and regression of the type of firm and cluster and the dependent variables.
In the case of a regression, your variables will be binary (e.g.;1 private, 0 public, 0 government).
A twist, maybe the industrial cluster and the type of the firm is not entirely independent (e.g.; in a region you have mostly governmental, in another region you have mostly private firms).
