Unit Test Section

Three unit tests:
1) Test if a data frame
2) Test the shape
3) Test docstring

    assert left.shape == stayed.shape

# Test docstring

Goal 3 for Summary Statistics

Caveats and mathematical notes:

Right hand skewed distribution (i.e. asymmetrical distribution) changes statistics. In future consider using median versus mean to accurately calculate statistical comparisons.

Equation for non-parametric skew:

$$\mu - \nu / \sigma$$

$$\mu= mean$$$$\nu = median$$$$\sigma = std$$
