I ran a survey where I showed 2 ads to men and women in 5 different countries to see which they preferred. I want to know if gender or country influenced the selection of a particular ad preference. The data is normal.

I was told to use a One-way ANOVA but I don't think this is correct as I have 2 numerical categories (number of people who selected each concept) and the rest are categorical - basically, I don't have 3 columns of numbers, only 2.

Then, I explored using a paired t-test, but i'm not sure how to perform this to see differences between ads AND countries - will I have to run multiple tests between 2 countries to find one with a significant difference?

Any advice would be fab!

Thanks
