Am I correct in assuming that you are interested in the Science Buddies project found athttp://www.sciencebuddies.org/science-f ... p032.shtml
I will attempt to start answering your questions on that assumption.
You ask "I realize I need google earth and I've used it but how exactly do you find the amount of globular clusters?" You do not use Google Earth to determine the locations of the globular clusters. You find the location, which for this demonstration is taken to be the Constellation in which the globular cluster is seen, from the data in the large table.
Also, you state "I have a data table but am struggling with it, I'm not sure it it is correct..." I think you may reasonably assume that the table provided in the project "materials" section is correct. If you wish to be extremely
rigorous you could check a few entries against standard catalogs, most of which are on line.
Finally, you ask "once you have which direction the globular clusters are pointing, how do you apply this to the data table?" I think you have gotten things in reverse. You use the data in the table to determine the locations on the sky (specified by the constellation's coordinates) in which the most globular clusters are found. Perhaps an analogy might clarify the concept here. Suppose you were in a strange city, looking for the airport. Because of buildings and trees, etc, you cannot simply look for the airport buildings in the distance with, say, binoculars. But you could look around and note in which directions you see a lot of airplanes flying around. Clearly, the direction of the airport would end to have many aircraft visible, whereas looking in the opposite direction you would expect to find fewer airplanes visible. If you wished, you could even systematically count the number of aircraft you see in the direction of each compass point (N,NE,E,SE,S,SW,W,NW): a plot of number vs direction should show a systematic increase in the number of airplanes spotted through your binoculars around some compass point -- and that would be a good guess as to the direction of the airport. In the astronomy case the globular clusters orbit (too slowly to see) around the galactic center just like the airplanes tended to fly around the airport.
Once you figure out in what constellations you find the most globular clusters, then you use Google Earth, to find out where those constellations are on the sky, and hence where on the sky the galactic center may be lurking beyond the dust clouds that obscure our direct view of the center (just like foreground stuff blocked our direct view of the airport). If you find Google Earth to be overwhelming, you could just as well use an old-fashioned paper star atlas that shows the brightest stars, constellations, and even some of the more conspicuous globular clusters. Most libraries have these star maps.
Please read over the procedure given in the project guide carefully. It is actually quite clear as to what exactly to do -- almost too clear since it doesn't leave a lot of room for you to figure out things on your own.
