Description

We have pretty good coverage so far https://codecov.io/gh/ropenscilabs/skimr/tree/master/R

but it would be great to get to 100% (or close to it). Most of them are easy tests for the individual functions in the stats.R file.
We could also use more tests of things like a column that is entirely NA.

Research direction
The issue asks to increase test coverage for functions in `R/stats.R`. Start by examining the existing tests in the `tests/testthat` directory to understand the testing patterns. Focus on adding tests for individual functions and edge cases like all NA columns. The Codecov report (https://codecov.io/gh/ropenscilabs/skimr/tree/master/R) shows current coverage gaps.
