Suppose the input wave meansData consists of the following 9 circular means:

To perform a non-parametric second order analysis (H₀: uniform distribution around the circle) execute the following command:

StatsCircularMeans/CI/T=1/NSOA meansData

As NSOA_Rp > NSOA_Critical H₀ (uniform distribution) must be rejected.

To perform a parameteric second order analysis (assumes that the second order quantities are taken from a bivariate normal distribution), execute the command:

StatsCircularMeans/T=1/CI/PSOA meansData

Here again H₀ of uniformly distributed data must be rejected.
