# How do I test a difference between two proportions representing fatality rate for Covid 19 in Philippines and World (except Philippines)?

I'm trying to analyse if the fatality rate from my country (A third world country) vary significantly from the world's fatality rate.

So I'd basically have two samples, labeled (Philippines) and (World excluding the Philippines) then i can compute the fatality rate for the 2 groups.

Does Mcnemar's test apply here for me to check if fatality rate in the Philippines is higher, or do you have any suggestions? Thanks

• What is the definition of fatality rate here? Mar 14 '20 at 5:31
• It's defined as Deaths / Cases Mar 14 '20 at 5:34
• Wikipedia's definition says it is the the same formula no matter which country. I also wouldn't directly associate a 3rd world country being threatened more by this virus, than any other countries, as long as there is no cure, the 3rd world countries actually should be threatened even less than others maybe. People in 3rd world countries don't travel that lot and they usually life in much smaller communities providing much less opportunities for the virus to spread. Mar 14 '20 at 5:41

Adding to a previous answer of applying an f-test (diff distributions) and/or z-test (diff means), I think it would help if you would group into age brackets and applied your analysis there too. Perhaps a certain population fares poorly in comparison while another fares well.
