Which test should I use



I have little knowledge of statistical tests. I am going to use SPSS. Please help me find the right tests for the following research objectives:

1. To determine the ratio of national to international sources of news in newspapers

2. To determine the ratio of local, national and international sources of news in English newspapers

3. To determine whether there is an association between the subject matter of a news story and the use of local sources.


If you alredy have the data for thousands of newspapers then you could just calculate basic stats like the median and 95% confidence intervals. I dont see the need for predicitve model based on you research questions. If you're collecting this data yourself just make a histogram. For the third question, you could fit a binomial model modeling the probability of using local sources as a function of various categorical variables (like did it involve health news, violent crime, whatever). Sorry, I dont know spss
