Is the population identified?
Are the samples representative of that population?

Is the population identified? No, but one can assume users of GEIS products
Are samples representative? Who knows?

What industry? Same or all different?
What age? Level of education?
Sample selection - One of convenience. No one wants that, but it is often necessary. It should be acknowledged.
Generalizability? We can’t tell.
