Just started using ArcMap - is this kind of analysis possible?

I have 2 files, a shapefile (.shp) and a raster file (.tif). The .tif is merely 2 bands (0 and 1) where 0 represents no forest loss and 1 represents forest loss (file is from here: http://earthenginepartners.appspot.com/science-2013-global-forest/download_v1.1.html) The .shp consists of polygons that represent protected areas (file is from here: http://www.protectedplanet.net/).

What I'd like to do is try a statistical analysis that would simply tell me how much forest loss ("1" points in the .tif) lies within the protected areas and how much loss lies outside the protected areas (in the .shp).

I'm wondering if it's possible to do this in arcmap/arcgis and if so how would I do this?

Sorry if this seems like a stupid question, I haven't been using the software for long and I couldn't find anything online.

If you're only dealing with points to raster, you can use Extract to Points http://resources.arcgis.com/en/help/main/10.1/index.html#//009z0000002t000000

I don't have anything to put into the "Input point features" that would be compatible. I only have a shapefile with polygons and a tif with 2 bands (loss and no loss/1 and 0) so I'm not sure how I'd make this work?

Ok, I think Darren's idea has the best shot, based on your analysis, but, he raised a very important point right at the beginning. You really have to define "outside" before proceeding. An example would be: In The Amazon Basin, what is the total area of forest loss inside and outside of protected areas? Then you would download an amazon basin shapefile to define your area of interest.

Thank you Sephe, Darren and Jayanta for your suggestions. I will try them all and see which works best for me
