How to extract representative random subsample from large sample?

I am new to SPSS and currently looking at data on family firms and non-family firms and their performance - I want to compare the group of family firms (70 firms) with non-family firms (25 000 firms). As you can see, the sample sizes are very different and I want to make them more similar. Therefore, I wonder how I can extract around 70 random firms from the 25000 non-family firms and still keep the same characteristics (such as standard deviation and mean) on key variables (as age, profitability, size etc.). This way it is a representative subsample, right?

Thank you for your time! :)

After reading another post it seems that a regression analysis was the best bet,
however I'm not sure it is applicable on my subject.

I want to research weather if countries are member of the european union has an effect on the number of companies created in that country for that year.

So I have all the data for 2004-2014 for the 27 EU countries on number of companies created.
Taking note that Romania and Bulgaria only accessed the EU in 2007 that will be an important year for our measurements.

But I'm not sure which kind of test(s) I need to use for this.

Thanks for your help :)

want to do an ordered logit regression. I have data from different sources and need to use the source as a selection variable for the dependent variable (only for the dependent variable, not for the regressors!).
I know how to do this for a linear regression. Is there a way to do this for ordinal regressions as well?

(I am researching whether past online ratings for retail stores influence future ratings.
I have a dataset of approx. 800.000 ratings. The unit of analysis is the rating given by person i to store s.)

Thanks for the help! :tup:
