Quick reminder ties or no ties

1. When there is rank ordered data, ties can occur.
When this is the case, you will use a Kendall’s Tau test.
Also, when the data is scaled (equal interval) and the distribution
is skewed (to the left or right), if there are ties in the data, then
the Kendall’s Tau test should be used.
Otherwise, use the Spearman Rho’s Ranking Test
