Number of features observed #20

Last Thursday you talked about the large number of features needed to ensure capturing all the characteristics for each graph (2^(n^2)) when applying statistical theory on graphs. So, as you told us, we have to choose a few features to compute and apply the statistical theory on them. I know by that we have discarded a lot of the features of the graphs, but is it necessary to test for all features? For example, if you choose a few features to observe and find that there is a significant difference between two groups of people. Is it not sufficient to say that you can distinguish between these two groups using these specific features only?
