Statistical test for effect of IV on DV between groups

Dear all,

I have a question regarding the statistical test I have to use for the following relation:

I want to study what the effect of size on performance is and if the effect of size is different for five different industries. Does anybody know what statistical test is sufficient for this?

Kind regards,

Some information would be useful. What do you mean
with "size" and "performance", how is it measured. And
who are the measured subjects? How large is your
sample size?

With kind regards
