Final answer:
Kendall's tau is used to measure the association between two variables and is relevant in fields like enzyme kinetics, represented by the Michaelis constant equation, Km = (k2 + ka)/k1.
Step-by-step explanation:
Kendall's tau provides a better estimate of the association between two variables. It is a non-parametric statistic used to measure the ordinal association between two measured quantities. A brief mathematical justification for using k/Km to judge enzyme perfection under steady-state conditions can be stated as follows: the Michaelis constant Km can be described by the equation Km = (k2 + ka)/k1, where k1 is the rate constant for the enzyme-substrate complex formation, ka is the rate constant for the non-productive binding, and k2 is the rate constant for the formation of the product from the enzyme-substrate complex. Therefore, Kendalls tau can be applied in contexts beyond enzyme kinetics where the relationship between two variables needs to be understood.
