Question 206

A neuropsychologist is comparing the average neural recovery rate (RRR) of patients undergoing an intensive new therapy to those receiving standard care (SSS). They find that the recovery rate for the intensive therapy is several orders of magnitude greater than that of the standard care.

To report this relationship concisely in their research report, which mathematical statement should they use to show that R R\,R is 'much greater than' SSS?

A

R∝SR \propto SR∝S

B

R≈SR \approx SR≈S

C

R≫SR \gg SR≫S

D

R≪SR \ll SR≪S
