# Does a greater Lyapunov exponent result in a more chaotic system?

Let $$\sigma_1$$ be the Lyapunov exponent of a one-dimensional system $$I_1$$ and $$\sigma_2$$ be Lyapunov exponent of one-dimensional system $$I_2$$. Can I say that if $$\sigma_1 > \sigma_2$$, then $$I_1$$ is more chaotic than $$I_2$$? Is it possible to compare a one-dimensional system with a two-dimensional system?
