[R] What are the common Standard Statistical methods used for the analysis of a dataset

[Greg Snow]

How can anyone overlook the intra-ocular trauma test (or sometimes called the inter-ocular concussion test).  But the i-o trauma test needs either a small data set or an appropriate graph of the data (or can you look at a dataset of a hundred columns and a million rows and do an intra-ocular trauma test?).  We were not told the size of the dataset or enough information to know what type of graph to make.

You do make a good point though that with minimal additional information the intra-ocular trauma test can be useful (well if it is significant, there are many datasets that fail the intra-ocular trauma test, but still yield interesting results after careful study).  And for any dataset that has a significant intra-ocular trauma test result, that should trump the results of SnowsCorrectlySizedButOtherwiseUselessTestOfAnything.
